I tried this earlier today, gprof doesn't seem to be able to trace the
extra time that's incurred due to the system calls. As far as gprof
was concerned, the --enable-pthread version was faster, even though it
took more system time and wall time. I also tried with gdb and set a
breakpoint on setprocmask but that didn't work - it only stopped on 4
calls to setprocmask, not millions.
