Hi, bug-bash.
>From a bash script, I'd like to be able to start several subtasks and
react to any one of them completing. I don't think I can do this with
the current bash. The `wait' function either waits on a specified subtask
to finish, or for _all_ subtasks to finish.
Am I mistaken about this perceived lack? If not, would it be possible
to add this functionality into bash?
The sort of thing I want to do with this is to perform lots of gzippings
in separate tasks, so as to spread them amongst the cores of my 4-core
processor, always keeping 4 subtasks on the go at any time.
