Thanks for the information.

You mean "undefine MALLOC_STACK", right? I don't see a way (in the
man page) to add MAP_STACK to malloc(2) memory, but I might be
missing something (again).

statethreads works when adding MAP_STACK:

...
#if defined (MAP_STACK)
  mmap_flags |= MAP_STACK;
#endif
  vaddr = mmap(NULL, size, PROT_READ | PROT_WRITE, mmap_flags, zero_fd, 0);


Thanks!
