Note that ManagedUserService does not depend on PO2TS at construction or
destruction time, so I don't think this is strictly necessary. It's fine with me
if it works now, but the last time I tried this, it caused some weird error at
construction time, because some service was created too early.

Got it.  I think the error was likely due to PO2TS depending on TokenSercvice,
which itself depended on other services.  I'll double check that this causes no
problems.
