What exactly is the problem with stacksize? Are you running out of
address space or don't you have memory overcommit enabled?
Because while the thread might get a few MB of stack only those pages
actually being used should get allocated by the kernel. So a new
thread might show 16MB virtual memory used for the stack the resident
memory will be just the few kiB being actually used (unless you do use
more and then a small stack would segfault).
