Here's a patch that makes Python-level lock acquisitions interruptible for py3k. There are many users of the C-level lock API, most of whom are not set up to deal with lock acquisition failure. I decided to make a new API function and leave the others alone.
If possible, I think this should go out with 3.2.
In that case, I was wondering if I should merge PyThread_acquire_lock_timed with my new PyThread_acquire_lock_timed_intr, since PyThread_acquire_lock_timed wasn't available in 3.1. Although it did go out in 2.7, we don't promise C API compatibility with the 2.x series, so I don't think it matters.
I've tested this patch on Mac OS X and Linux. The whole test suite passes on both, along with the test that I added to test_threadsignals.py.
I added a noop compatibility wrapper to thread_nt.h, but I haven't tested it or built it. When I get around to testing/fixing the subprocess patch on Windows, I'll make sure this works and the test is skipped.
