@ -187,10 +187,9 @@ The :mod:`signal` module defines the following functions:
Send the signal *signum* to the thread *thread_id*, another thread in the same
process as the caller. The signal is asynchronously directed to thread.
*thread_id* can be read from the :attr:`~threading.Thread.ident` attribute
of :attr:`threading.Thread`. For example,
``threading.current_thread().ident`` gives the identifier of the current
thread.
Use :func:`threading.get_ident()` or the :attr:`~threading.Thread.ident`
attribute of :attr:`threading.Thread` to get a 'thread identifier' for
*thread_id*.
If *signum* is 0, then no signal is sent, but error checking is still
performed; this can be used to check if a thread is still running.
