stopfork trick (was: radiusd: Error detected by libpthread: Invalid mutex.)

Can you elaborate how this is done?
I gdb'd radiusd, set a breakpoint on main and let it run.
When it hit the breakpoint, I looked up the debugged radiusd's PID and did
sysctl -w proc.XXXX.stopfork=1
and let gdb continue. The main process exited, but I would expect to find a
child in ps output. Or are these stopped childs hidden from ps? If yes, how
do I learn their PID to attach to them?
Or what am I doing wrong?
