I had a similar issue with Lyris running under Linux emulation (until
they came up with a FreeBSD native version).  

What was happening was that Lyris was creating and destroying dozens
of threads.  Under linux emulation, these are kernel threads, and
treated as processes by the kernel.  However, the linux apps don't see
fit to reap these processes, as linux does it automagically.  

The only real fix is to make the app reap the zombies periodically, or
convince opera to come out with a fbsd native version.
