With the FBT provider as it now stands and using this script:

fbt:::entry
{
        @[probefunc] = count();
}

the output after a buildworld is listed below. Check out the number of
calls to critical_enter and critical_exit (which are listed at the bottom)!
And for comparison, check the hardclock() count which relects 1000 Hz.
