I have the corresponding munmaps.

Im generating full traces now separated by threads, with each thread
logging in a different file. So I belive we will be able to nail down
exactly what the hell is going on.
I've also changed mupdate_workers options to the following values:
mupdate_workers_start: 50
mupdate_workers_minspare: 50
mupdate_workers_maxspare: 50
mupdate_workers_max: 50
to make sure I dont end up with 100000s strace files to look into.
