SPAWN background command without nohup? [message #88861]

Dear Folks,

Using SPAWN to start a background process on unix-like systems
can leave the process running even after the IDL process terminates.
I'd like to arrange things so that the child process is killed when IDL exits.

Here's a schematic example:

IDL> spawn, 'myprocess &', pid=pid
IDL> print, pid
62417
IDL> exit

$ ps | grep 62417
grier 62417 0.0 0.1 2473856 12320 ?? S 10:41AM 0:00.02 myprocess

This is similar to running a shell command with nohup:
$ nohup myprocess &
$ exit

Is there a way to make IDL spawn a child process that terminates when
the parent IDL session terminates?

All the best,

David
