CPU usage gone to 0.

Definitely.
When explorer is hung and TSVNCache is then killed, TortoiseShell
immediately throws a message in the debug log saying "Pipe ReadFile
failed". So I guess that explorer calls TortoiseShell, which reads
something over a pipe from TSVNCache, which hangs.

That's with the version from a couple of days ago.
The new version just overloads the debug log with a lot of crap where
I don't know what's what :-).

Luckily CPU usage is very, very low when this particular bug's triggered.
