On Windows, Lock.acquire() (and other synchronization primitives derived from it, such as queue.Queue) cannot be interrupted with Ctrl-C, which makes it difficult to interrupt a process waiting on such a primitive.
Judging by the code in Python/_thread_nt.h, it should be relatively easy to add such support for the "legacy" semaphore-based implementation (by using WaitForMultipleObjects instead of WaitForSingleObject), but it would be much hairier for the new condition variable-based implementation.
Of course, many other library calls are prone to this limitation (not being interruptible with Ctrl-C on Windows).
