It is not really a matter of performance, but of technical
implementation. I wouldn't feel particularly happy about implementing a
class derived from QPopupMenu that fills it up during an overridden
show(). It might work but I don't think it's a robust technique (as it's
definitely unusual, we could expect it to break with various qt versions
...)

When does Menu::update() get called exactly ?
If this works with a reasonable "frequency", i.e. we can avoid the
update-on-menu-open behaviour, then I'm happy.
