The \module{autoGIL} module provides a function \function{installAutoGIL} that
automatically locks and unlocks Python's Global Interpreter Lock
when running an event loop.

\begin{excdesc}{AutoGILError}
Raised if the observer callback cannot be installed, for example because
the current thread does not have a run loop.
\end{excdesc}

\begin{funcdesc}{installAutoGIL}{}
        Install an observer callback in the event loop (CFRunLoop) for the
        current thread, that will lock and unlock the Global Interpreter Lock
        (GIL) at appropriate times, allowing other Python threads to run while
        the event loop is idle.
        
        Availability: OSX 10.1 or later.
