Sean, if I am not mistaken, supervise opens a pipe and gives that pipe's
filedescriptor to processes before exec'ing the new program.

Many daemons are programmed to walk the list of available file
descriptors and close them --- based on a wise suggestion in Steven's
Advanced Programming in the Unix Environment.

If ftpd does this, as I fully expect it does, supervise will think ftpd
dies as soon as ftpd closes the filedescriptor with the pipe.
