Well, explaining the internals of the cache is IMHO Wills job here. He's
the one who started it ;)

As of revision 2915, I added some OutputDebugString() functions which
you can catch with the Dbgview tool from sysinternals. Of course, only
very few messages are written there, otherwise we would get too much
information and would have a hard time filter those.

So that means it hung when you right-clicked, not on startup. Hmmm - the
context menu extensions and the overlay handlers are different COM
objects, so it's possible that those tried to access the cache at the
very same time...
