The programs I see that are comfortable spawning processes willy-nilly on
windows are mostly .net, which has a lot of the runtime assemblies cached by
the OS in the GAC - if you are spawning a second processes of yourself, or
something that uses the same libraries as you, the compile step on those can
be skipped.  Unless you are talking about python/non-.NET programs, in which
case, I have no answer.
