https://github.com/dlang/druntime/blob/master/src/core/thread.d#L4328
allocates fiber stack using mmap / malloc / VirtualAlloc and doesn't
seem to register that memory in GC. But that may be indirect result of
https://github.com/dlang/druntime/blob/master/src/core/thread.d#L4439
call, which is why I am not sure.
