I prefer your earlier idea (getting the umask at program start). Reasons 
why:

1) mutexes are expensive
2) you protect only KTemporaryFile, but *ALL* other file creations in 
other threads (QFile, creat(2), open(2), QTemporaryFile, Unix sockets) go 
unchecked
3) it's highly unlikely that anyone changes the umask during the program 
execution anyways. (but they do create files)
