Could all four new handlers use PTS_WRITE_MSG() and _exit() instead?
printf() and exit() are not async-signal-safe. Since SIGSEGV is raised while
libc is processing the invalid timer ID, calling them invokes undefined
behavior and may hang instead of reliably reporting a pass.

Verdict - Needs revision
