Isn't there a more essential difference ? Namely that exec() overlays the 
current program and therefore never returns, while spawn() may be used in 
that way but also so that it returns. At least that's the way it's 
implemented by Watcom and Borland.

Since exec() never returns on success, it would seem pretty difficult to me 
for it to return any status whatsoever upon successful execution.
