Signal handlers have always been called asynchronously, so there's been
some fuzziness as to when statprof handlers get called; in practice
however it's corresponded pretty well.

I just ran the statprof unit test and it seems to still be OK. Perhaps
in Julien's run, there simply was not enough time in user space relative
to the sampling frequency. (Certainly statprof should deal with this in
a more intelligent fashion.)
