Robert Shearman f8a2edb805 - Split up apartment creation so that the long code paths that don't
need locking no longer have locking.
- Add special cases for the threads that join apartments but can't
  increase the refcount of the apartment.
- Free TLS storage on thread destruction (including releasing the
  apartment the thread is in, if any, and so making another test
  pass).
