If it makes _sense_ to have more than one algorithm, e.g. when each
outperforms the other by a nontrivial margin (depending on the data),
then there's not much sense in saying that it's stupid to do it.

Right now Linux 2.1 is in the fridge; this means that there are
considerations beside "the technically most superior solution".
Linus has said as much.

Assuming that there is one. You're welcome to implement a dynamic hash,
for instance, but Linus did say that if anything gets into 2.2 it's going
to be the AVL stuff. If you can convince him otherwise, your solution may
well be superior -- I'm not saying it isn't.

Perhaps the biggest disappointments were the ones you expected anyway.
