  50  * We really should be careful with the number of fd's that this routine
  51  * opens:  the ch_seq ch_table.c module likes to keep 6 (yes, SIX) fds around
  52  * to speed-up host lookups in the channel table.  Unfortunately, after all
  53  * of them get opened, six are always open (ch_table may close one to open
  54  * another).  The bottom line is that if repl calls post, then we get 12
  55  * (yes, TWELVE) fds open, with only six usable.
  56  *
  57  * send will close all fds >= 3 prior to invoking post.  It would be nice
  58  * if one could control ch_seq's use of fds for table lookups, but such is
  59  * life.
