DESCRIPTION
    This module provides primitive operations to manage Python interpreters.
    The 'interpreters' module provides a more convenient interface.

FUNCTIONS
    channel_close(...)
        channel_close(cid, *, send=None, recv=None, force=False)

        Close the channel for all interpreters.

        If the channel is empty then the keyword args are ignored and both
        ends are immediately closed.  Otherwise, if 'force' is True then
        all queued items are released and both ends are immediately
        closed.

        If the channel is not empty *and* 'force' is False then following
        happens:

         * recv is True (regardless of send):
           - raise ChannelNotEmptyError
         * recv is None and send is None:
           - raise ChannelNotEmptyError
         * send is True and recv is not True:
           - fully close the 'send' end
           - close the 'recv' end to interpreters not already receiving
           - fully close it once empty

        Closing an already closed channel results in a ChannelClosedError.

        Once the channel's ID has no more ref counts in any interpreter
        the channel will be destroyed.

    channel_create(...)
        channel_create() -> cid

        Create a new cross-interpreter channel and return a unique generated ID.

    channel_destroy(...)
        channel_destroy(cid)

        Close and finalize the channel.  Afterward attempts to use the channel
        will behave as though it never existed.

    channel_list_all(...)
        channel_list_all() -> [cid]

        Return the list of all IDs for active channels.

    channel_list_interpreters(...)
        channel_list_interpreters(cid, *, send) -> [id]

        Return the list of all interpreter IDs associated with an end of the channel.

        The 'send' argument should be a boolean indicating whether to use the send or
        receive end.

    channel_recv(...)
        channel_recv(cid, [default]) -> obj

        Return a new object from the data at the front of the channel's queue.

        If there is nothing to receive then raise ChannelEmptyError, unless
        a default value is provided.  In that case return it.

    channel_release(...)
        channel_release(cid, *, send=None, recv=None, force=True)

        Close the channel for the current interpreter.  'send' and 'recv'
        (bool) may be used to indicate the ends to close.  By default both
        ends are closed.  Closing an already closed end is a noop.

    channel_send(...)
        channel_send(cid, obj)

        Add the object's data to the channel's queue.

    create(...)
        create() -> ID

        Create a new interpreter and return a unique generated ID.

    destroy(...)
        destroy(id)

        Destroy the identified interpreter.

        Attempting to destroy the current interpreter results in a RuntimeError.
        So does an unrecognized ID.

    get_current(...)
        get_current() -> ID

        Return the ID of current interpreter.

    get_main(...)
        get_main() -> ID

        Return the ID of main interpreter.

    is_running(...)
        is_running(id) -> bool

        Return whether or not the identified interpreter is running.

    is_shareable(...)
        is_shareable(obj) -> bool

        Return True if the object's data may be shared between interpreters and
        False otherwise.

    list_all(...)
        list_all() -> [ID]

        Return a list containing the ID of every existing interpreter.

    run_string(...)
        run_string(id, script, shared)

        Execute the provided string in the identified interpreter.

        See PyRun_SimpleStrings.
