A few more details on this: I use the "DesktopProcess=1" registry
setting to cause Windows Explorer to run one process for the Desktop
and a separate process that handles all other Explorer instances (this
is sometimes useful when you are developing Shell Extensions).

I notice that the "normal" case of selecting at least one drive type
to have overlays results in TSVNCache starting up along with system
startup (or login), and being owned by the desktop explorer.exe.

However, when NOT selecting any drive type for overlays (relying
solely on Include paths), no TSVNCache instance is started until the
first Explorer window is displayed that includes an Included path. As
this type of startup yields the same results as killing the TSVNCache
instance after disabling all overlay drive types (TSVNCache being
started "late" and not being owned by the top-level Windows Explorer),
perhaps there is a connection?
