D, Darwin : Do not allow moving fibres between pthreads.
Emulated TLS targets (and, indeed some native TLS ones too)
on GCC should not allow fibres to be moved between threads
since the ME keeps pointers to TLS vars cached as an internal
detail and cannot see that a function call could return on a
different thread.
