We're 2 weeks past the feature freeze and you're proposing an entirely new and 
separate class, without requiring changes in any of the public classes that 
will be in 5.0. 

So this new contribution is Qt 5.1 material.

Aside from that, I understand the need for a timer window. When we suggested 
merging with QTimer it was to check if that is possible. If it doesn't turn 
out to be, then so be it, a new class is born.

Your contribution is also sorely lacking implementation for other platforms, 
including the reference ones. Please provide such implementation or document 
that the platform has no such feature.
