From: Tvrtko Ursulin <tvrtko.ursu...@intel.com> It was observed both on Linux and Android that tests which fork can sometimes hang failing to terminate child processes.
This was eventually tracked down to race conditions in C library implementations, all with regards to caching of PID/TGID and TID values. Solution is to revert the previous workaround, which closed the race under glibc a bit, and ensure current values from the kernel are used during timing sensitive periods. This was tested under Android only but should be a generic fix.
