One thing to be careful about with UnhookWindowsHook: for at least
some hooks, calling this routine causes Windows to generate one
last call to the hook routine, with the ncode parameter set to -1.
You need to be prepared to handle this case: you not free the
ProcInstance until UnhookWindowsHook returns, and your hook routine
(when it receives this code) must call DefHookProc.
