Yah, I hadn't thought about csh. Definitely agree the rule should be
/bin/bash, or /bin/sh for scripts that were tested with ash.

Interesting. Never even occurred to me to test performance, I expect
interpreters to be slow, and at least subconsciously I was aware that bash
is bloated... but wouldn't have guessed ash would be *that* much faster.

Hm. I just now thought I'd try a couple of things in ash, as an
interactive shell, on slack64 13.1, and the damn thing segfaulted halfway
through typing the first command. /me runs off to do some more testing...
