   I just took a look at the code again, and maybe I'm missing something,
   but is there any reason why the handles could not be handed back to
   the master when all of the slaves close the pty?  The master would
   then have an extra couple of handles that may or may not ever be used
   again but if a child requests the pty it would be able to retrieve
   the handles.

The desired effect is to close all the write handles to the pipe, so
that the master, which is hanging in read, gets an EOF.  Copying the
handles back to the master will not achieve this effect.
