I don't want a kernel process hashing and comparing pages while I'm
trying to watch a movie to determine which ones it can combine... The
extra bookkeeping is just a bad idea.

Nope, it won't. Modules from static libs will not be in the same
page-boundary-relative locations in different binaries; moreover, only
the needed .o files will be included, and they'll each be patched with
different relocations. I don't see any way this could work..
