I confirm the speedup with this new build: on this pathological Vista
virtual machine I have the delay on startup has shrunk down to 8
seconds. On a real XP box the delay is less than 1 s.

Perhaps it would be illuminating to look at the changelogs of
wxWidgets to see what could possibly cause this effect, and also test
whether it appears on non-Windows platforms.
