Retry if interrupted before mMessageThread has joined

Bug: 24342101

If interrupted during mMessageThread.join(), retry the join instead of
assuming the thread has joined and continuing.  Continuing to destroy
the context will cause a segfault when the message thread attempts to
use the destroyed context.
