We map each thread's stack by creating an area on demand (3 stack
pages + 1 guard page, so 16KB altogether), so the only practical limit
is either a) exhausting the available address space, or b) hitting the
system-wide thread limit of 4096. I'd wager you'd hit the latter
before you hit the former, since even a full 4096 threads would equate
to ~64MB of total memory usage. The system-wide limit could, as far as
I'm aware, be lifted higher if desired with a few trivial changes.
