Oh, please no. Imho, these two have nothing to do with each other.

Besides, at least on x86 tracehook_signal_handler's logic is not exactly

And we are going to kill tracehook.h. While personally I do not think
this is the good idea, but the matter of fact is that tracehooks are
already destroyed.
