I don't see a problem here. We don't remove hook when chain is in use.
However calling server means we'll have to call server one more time.
That's on top of 5-6 calls already.

But also the problem is passing information between threads here. We have
to continue with the hook chain, so we need to tell next thread at least
what hook is it (pass a handle?). Otherwise we won't know which one is
the next. But that gets us back to the same problem...
