well I made 10 copy's of threadbug and run them in parallel. In my case
libpthread does not allocate a 10 Mb memory block, because
the 10 processes should allocate 100Mb of memory Top does show only a
sligth increase in memory . On my kubuntu there are
145 processes allocated . So i can not reproduce your problem.
I just tried on another distribution, and without WaitFor the leak is still
there, but a lot smaller, only ~12kb per thread.
Did you run with or without WaitFor?
How big is the thread overhead?
Thanks!
