Subject: In the unix backend, when implementing the defenses against small
 file descriptors, delete a file just created if it was opened with
 O_EXCL|O_CREAT so that it can be created again the next time through the
 loop.  Fix for the problem described by
 [forum:/forumpost/699af709ab3a8ccf|forum post 699af709ab3a8ccf].
