Windows 95, 98, Me and NT4 are on their way to deprecation as of Qt 4.5. 
We have not tested Qt 4.5 on those systems (yet) and, from Qt 4.6 on, they 
will not be supported at all.

In any case, even Windows 95 does house-cleaning when an application exits 
(excepting, of course, platform bugs). Even DOS did that, albeit in a much 
simpler way.
