1> Currently, depending on the value of SERVER_HOME_DIR, server
   creates its pipe in /tmp or the homedir.  I presume that /tmp was
   added for people who started multiple emacses at a time on
   different hosts.  Unfortunately our diskless machines share /tmp.
   It would be better if this mode added the hostname to the pipe
   name.  Any system with BSD pipes will have pathnames long enough to
   handle the catenation of uid, hostname, two dashes, and "esrv".

2> Unfortunately server.el can only gc unneeded pipes if they are in
   the homedir.  Since there's no clean way for the elc to learn of
   the compile-time option of server.c and emacsclient.c, using /tmp
   might as well be made the default.
