I wanted to check in and see if there was a chance of this feature being accepted upstream before I spent any time on it... so here goes. The "wait [n]" command is handy, but would be even handier is: wait [[-a] n] instead, which asynchronously checks to see if process 'n' has completed.
What's wrong with using the existing 'kill -0 pid' to check if pid still exists, rather than inventing a new argument to 'wait'?
