Not easily at all, which is a real difficulty with the whole business of
shell extensions. You could look at what TSVNCache is doing at the same
time. (Perfmon would be more useful here.)

There are so many ways for addons to hook into the shell, and they're often
called at quite unexpected times.

When I was still working on TSVN, I wrote test harnesses which could load
the shell extension directly (i.e. rather than Explorer.exe loading them)
and this made it easier to do profiling, but it's easy to get fixated on
one kind of simulated workload and miss some real-world scenario.

One could imagine writing a tool which identified all the installed shell
extensions, and then redirected them all via some kind of instrumentation
shim which could then give profile-like stats for their use. Might be
interesting to do...
