Well, this code comes from ktempdir.cpp which uses umask too.
And we never really checked which kdelibs classes are threadsafe, but it's not too late to start I guess.

In both classes, all we want is to "get" the umask, not to set it. How about we get the umask in some
code called during initialization, like the KGlobalPrivate ctor, and we add a KGlobal::umask() accessor?
