[Beowulf] looper

[Dan Stromberg]

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.

I hope someone finds it useful.  I know I have.
