Correct. The "*" means it will be wrapped in a shell (/bin/sh), the "&" 
means it will not block the thread that ran it, and "timeout=0" means it 
will be allowed to run indefinitely, until it terminates on its own, or 
some external thread decides to terminate it.

Is it possible that being wrapped in a shell, the run environment is not 
exactly what you expected, and that is causing some relative paths to be 
incorrect?  Perhaps `irsend` is not in the path? It's not a login shell, 
so the environment should not be substantially different, but it's work 
investigating.
