Fix bug in OS2_receive_message.  It's possible to arrive here with a
closed qid due to race conditions when the sending thread closes the
qid while the reading thread is about to read from it.  This was
happening under some circumstances when sending mail: the sendmail
program doesn't generate any output, and if it terminates before the
input thread's first read, the qid will be closed.
