Dmitry Vyukov e797203fb3 selftests/timers/posix_timers: Test delivery of signals across threads
Test that POSIX timers using CLOCK_PROCESS_CPUTIME_ID eventually deliver
a signal to all running threads.  This effectively tests that the kernel
doesn't prefer any one thread (or subset of threads) for signal delivery.
