Frankly I was using nohup program my whole life. So it looks like disown 
works the same, except it does not store output in a file. Plus its a 
builtin - no need of external command from coreutils.

There is one advantage of disown - it seems it does not consume SIGHUP, 
it just tells bash not to send it on exit. Therefore one could send 
SIGHUPs to the rails to reload the configuration. Not sure if it support it.

Never heard of it. Thanks.

For others (from the bash man page):

disown [-ar] [-h] [jobspec ...]

Without options, each jobspec is removed from the table of active jobs. 
If the -h option is given, each jobspec is not removed from the table, 
but is marked so that SIGHUP is not sent to the job if the shell 
receives a SIGHUP. If no jobspec is present, and neither the -a nor the 
-r option is supplied, the current job is used. If no jobspec is 
supplied, the -a option means to remove or mark all jobs; the -r option 
without a jobspec argument restricts operation to running jobs. The 
return value is 0 unless a jobspec does not specify a valid job.
