Hmmm.... may I ask why?  Unifying hooking mechanism seems like a good
idea to me and it's not like it's gonna add any runtime overhead
although it does complicate init/exit but well that's something you
have to pay if you wanna do things dynamically and sans the ifdef
stuff it's like a couple hundred lines of isolated code.

Thanks.
