The problem is polling is pretty detrimental to power saving on modern CPUs. There might also be a performance impact that makes things worse :-) More generally, we really would like locks to be interruptible under Windows, as it would be useful in many more situations than joining threads. Unfortunately, as you have discovered we have several lock implementations for Windows right now. The SRWLock one is probably difficult to make interruptible, but it's never enabled by default. The Semaphore one looks legacy, so could perhaps be removed. Remains the condition variable-based implementation. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue21822> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
