No, I have nothing to say about malloc/mmap/etc. I just want to add some
balancing positiveness to offset my usual polemics. Torvalds harps on
optimizing for the common case all the time. This little voice with a
faint scandanavian accent in the back of my head keeps saying "optimize
for the common case". It is a wise little voice. The common case is
usually beyond the ken of a compiler, it's something a human has to
know, it works, can pay off huge, and works with anything from assembly
to Bash.
END BROWNNOSE
