"Never" is too strong here. In some circumstances, it might work.

Even though we say undefined, there is actually a very well-defined order of 
destruction, given the load order and the object-creation order. So in some 
circumstances it might reliably work.

This isn't about QProcess. This is about any static non-POD, so it really 
doesn't belong in QProcess's documentation.

Our recommendation is that you don't use ANY static, unless it's a POD or POD-
like type (or at the very least has a trivial destructor).
