Slightly OT .... FWIW ....
One quick-and-dirty way to check threads for any process is to use the
ncurses-based 'htop' utility. I much prefer this to 'top' for several
reasons, including its ability to hide/display kernel threads,
hide/display user threads (in a different color if you like), display
with vertical and horizontal scrolling, assign processor affinity on the
fly, ptrace/strace processes, and a lot more.
It's in Dag Wieers' rpmforge repository for CentOS.
The suggestions offered in this discussion are all very useful with
regard to tuning Apache.
