It would be trivial to change this. As I consider it unlikely that this
will make it into the kernel, I'm not going to bother to make it more
standardized, as I find it to be most useful as it is and I don't feel like
recompiling lshell. :)

That's what I expected.

It's not threaded at all. Is there any way to have it yield if it doesn't
use kernel_threads? I really don't know much about in-kernel scheduling.
