Actually, that patch was allready comitted. Looking at the ktrace, I just
assumed that is where the problem lied, but if the linux libc should work
properly with mremap failing, then maybe thats not the problem at all.
Quake2 does use mmapped audio, so maybe quake2 is calling the mremap
Thanks, I'll keep looking.
