I believe the kernel and/or GCC uses a particular method of rewriting the
stack with executable code to implement function callbacks, called a
"trampoline". It is considered hairy black magic by all involved, even the
people who implement them, but I guess it gets you some benefit.
The Jargon File <http://www.jargon.org> has an entry for them.
