  This means that when an executable is first mapped in, the kernel will
  slurp the whole thing off disk in one hit.  Some IO changes were made to
  speed this up.

Does this just pull in text and data, or will it pull any debug sections
too?  That could fill memory with a lot of useless junk.

Just text, I expect.  Unless glibc is mapping debug info with PROT_EXEC ;)

It's just a fun hack.  Should be done in glibc.

Well, fun hack or glibc to-do list candidate, I hope it doesn't get
forgotten.

I have to pull the odd party trick to get people to test -mm kernels.

This reminds me of something I've not looked into for some time.

Being an active user of the 2.5 series including -mm, should I have
updated glibc, or is there nothing new enough yet to warrant that?

Maybe I should just ask the glibc people. Wasn't sure what the proper
forum was.
