The "right" way is with 'open process'.  The last I looked 'open 
process' does not work at all on OS X.  I tried shell() to a named 
pipe, but have had no success, but that is probably my ignorance.  I 
have tried using shell() to spin off a process, but I have not figured 
out how to do that.  (I mention these, because someone might know how 
to get around those.)

I have run processes from an external, but I have always waited for 
them to quit.  I think there is probably a way to do this with an 
external.
