I was asked by my employer to publish this a bit ago, so here it is: http://stromberg.dnsalias.org/~dstromberg/looper/
It's a multithreaded script for running n POSIX shell commands m at a time with good error checking. It allows for things like stashing in ssh $hostname or rsync $hostname in a convenient way - with pretty complete shell quoting so that your command comes out on the other side of the ssh command the same way it went into looper. It also allow I hope someone finds it useful. I know I have. Followups have been directed to comp.unix.shell. -- http://mail.python.org/mailman/listinfo/python-list
