The thread_foobar.h reference for the interface for abstracting the platform-specific thread implementation does not include newer features such as timed locking and TLS support.

You may want to provide an implementation of PyThread_acquire_lock() that simply defers to PyThread_acquire_lock_timed() (see thread_pthread.h, which does the same).

Added an example of deferring to PyThread_acquire_lock_timed in PyThread_acquire_lock. Also fixed a mistake in the string of a dprintf in PyThread_acquire_lock_timed.

Hum, your comment about deferring is wrong, since thread_nt.h also does the deferring:

PyThread_acquire_lock(PyThread_type_lock aLock, int waitflag)
    return PyThread_acquire_lock_timed(aLock, waitflag ? -1 : 0, 0);

Oops... I removed that and just put the deferral in there.

Thanks! The patch looks good to me, I'll let it sleep a bit to see if other people have an opinion.
