Locks can't blindly release themselves because they find themselves
running in another process.
If anything if a lock is held and finds itself running in a new
process any attempt to use the lock should raise an exception so that
the bug is noticed.
I'm not sure a PID check is good enough. old linux using linuxthreads
had a different pid for every thread, current linux with NPTL is more
like other oses with the same pid for all threads. |
