As always, please send me a testcase if you want me to look at it. The
implementation of gprof is pretty complete, but there may be a priority
issue for the thread that actually does the profiling. I'll see if up'ing
the thread priority will fix your problem or not.

This looks ok to me. You should look at gcc's docs for profiling options
(not just -pg, but also a few others there as well), and docs for gprof
(I just realized that I missed the gprof docs in my distribution, but
you can get those online at http://www.delorie.com/ and many other
places).
