I found two causes of flakinness: - SIGPROF signal isn't delivered to a process; - Profiler thread (the one that retrieves tick events from the queue and writes to log) doesn't get a CPU; Both are fixed. The script from bug description with run count increased to 200 runs without any test failures. OS X and Windows are unaffected because they don't use signals mechanism.
