I've just remembered, I nicked "w32Func(jJumpto" from rundemos.exw
(the one that comes with win32lib) for use in MEditor, I think it got
rid of an annoying dos window briefly appearing when using system().

AFAIK, system_exec() always waits for the command to complete before
returning the exit code from the program.
