TODO for htimp		3.Dec.93

- Before exiting (e.g. from signal), kill all child processes.

- Add SET_I etc. types to gconf.
- Add "initialoutput" (bool/int) to appconf, use to determine whether
  to expect any output from the program before we send input (default 1).
- Add log file which records start/end of each job.

- Add "mastertimeout" that specifies that server should exit after being
  idle for that long with no requests and no data (i.e. everything cleaned up).
- Make 'kill -1' reread conf file and app conf dir.
- Only allow connections from local machine.
- Add debug command line option to connect to server and send it requests.
  (for things like, dump a list of all current jobs)
  Better still, make it a regular HTTP request, but use conf file to limit
  who has the right to execute that request (can httpd support this?).
- Add request /i/handle to dump current info about that handle.
