[Bug 248225] Linuxulator: pthread_join crash

--- Comment #1 from Alex S <iwtcex at gmail.com> ---
Turns out pthread_join in glibc calls this bit of code [1]:

  if (__builtin_expect (stack_cache_actsize > stack_cache_maxsize, 0))
    __free_stacks (stack_cache_maxsize);

Consequently, `limit stacksize 8192` (the default value on Linux) gets rid of
crash.
