Do you happen to be running a multi-CPU system?
I recently experienced a similar thing with a threaded perl-script using
~120% CPU on a
dual AthlonMP. (and perl was, of course, built with ithreads)
My assumption is that FreeBSD is now able to spread a process's threads
among multiple CPUs.
If so, I am never getting a single-CPU for a desktop system again. =)
Oh yes, my /etc/libmap.conf:
libm.so.2       libm.so.3
libc_r.so.5     libpthread.so.1
libc_r.so       libpthread.so

Kind regards,
