You're right.  That's what I get for posting from memory instead of from a
file.  I did figure out that I needed to use stdin and skip the
translate-to-socket model.

Here's the code in its most recent incarnation.  This prints "Got empty
buffer" forever.

import os
import sys
import time

log = open('/tmp/tinetd.log','a')
sys.stderr = log
sys.stderr.write( 'Hello\n' )

# Suck all data from the socket until a line ends with Ctrl-D.

bfr = ''
while 1:
  bfr1 = sys.stdin.readline()
  if bfr1:
    log.write( "Got %d\n", len(bfr1) )
    bfr = bfr + bfr1
    if bfr[-1] == chr(4):
      log.write( "Got ctrl-d\n" )
      break
  else:
    log.write( "Got empty buffer\n" )

log.write( repr(bfr) )
log.write( '\n' )
