Accessing a lock object in a C module

[Konrad Hinsen]

For a threaded application, I need to access a lock both from Python
code and from a C extension module, but I haven't yet found a way to
do that.

If I create a lock object in Python via the thread module, I can't
access its lock_lock member; the structure definition is not in a
header file, and there is no C-level access routine either. Inversely,
if I create a lock in a C module, I can't create a corresponding lock
object accessible from Python.

It seems that the only solution is to use PyObject_CallMethod on the
lock object in my C module, which means additional interpreter overhead.
Has anyone found another method?
