Actually, it behaves the same way. That is, it instructs the
OS to load and execute a particular executable. On Linux, that
executable is not... well... executable.

In my own app, I detect that I'm running under mono and use
mono.exe as the program to run, putting my target exe in
place of the first argument. It's the only approach I've been
able to make work consistently. If there's a better way to
do that, I'd love to know about it myself.

OTOH, I agree that hanging on the call is a problem in itself.
I'd expect a failure.
