I am curious, what do you see when you strace it?
On Linux you get:
write(1, "Start\n", 6Start) = 6
setitimer(ITIMER_PROF, {it_interval={0, 0}, it_value={1, 0}}, NULL) = 0
--- SIGPROF (Profiling timer expired) @ 0 (0) ---
setitimer(ITIMER_PROF, {it_interval={0, 0}, it_value={1, 0}}, NULL) = 0
rt_sigaction(SIGPROF, {0x7d3df0, ~[ILL TRAP ABRT BUS FPE KILL SEGV CONT
STOP TSTP TTIN TTOU SYS RTMIN RT_1], SA_RESTORER|SA_SIGINFO,
0x7febc4d9ac60}, NULL, 8) = 0
rt_sigprocmask(SIG_UNBLOCK, [PROF], NULL, 8) = 0
write(1, "Shutdown\n", 9Shutdown) = 9
setitimer(ITIMER_PROF, {it_interval={0, 0}, it_value={0, 0}}, NULL) = 0
close(2) = 0
close(1) = 0
I assume you don't get the "timer expired" at all there?
