Profiler's SIGPROF handler is NOT supposed to run for a long time.  If
you disagree, please show the code called from the handler that can
run for a long time.

Or maybe I misunderstood you suggestion (or that of Gerd): to me,
"while profileing" means just while the profiler's SIGPROF handler
runs, nut the whole time profiler is active.
