Yes, it is not quite common. But i am trying (succesfully so far) make 
preemptive multithreading using coroutines and yielding in count hook 
after given time. Plus I am writing debugger which uses line hooks. 
Turning the debugger off is mostly about not registering line hooks 
(call & return as well) so it is comfortable for me to have both hooks.

After some tests it looks functional. At least i didn't spot any side 
effect. Can you fix it in future releases, please?
