    This is a Feature not a Bug. If you leave descriptors open the process
    could conceivably read or write to/from them, so sshd will wait for them
    to close.

    With Redhat 9's nohup, this is stdin. If I do "sleep 500 & exit", I get:

    $ lsof -p 9241
    COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME
    [snip]
    sleep 9241 dtucker 0u CHR 136,7 9 /dev/pts/7
    sleep 9241 dtucker 1w REG 3,2 0 3606295 /home/dtucker/nohup.out
    sleep 9241 dtucker 2w REG 3,2 0 3606295 /home/dtucker/nohup.out

    The minimum command line to to what you want is therefore:
    $ nohup sleep 500 </dev/null & exit

     Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
