Don't run the destructors directly after executing the user thread

the pthread thread model).
So then my patch is no longer necessary, because the __thread tls_dtors
will still be valid? +1
I think your patch still is good to have, in any case. As long as __thread
is implemented with native TLS, the current code is pretty neat, but with
emutls, it's pretty messy, so I think your patch simplifies the design in
general.
