Why do you need to save it in temporary file at all? Why don't you
read the output like gitk does?  You can take a look at popen(3). It's
known to be portable among operating systems and libc's.  Or, BTW, why
don't you just read qprocess.h, use processIdentifier()/pid(),
read*()-methods and the like?  (though, looking at the QProcess in
qt3, I wouldn't really blame you)
