Would it be useful to write manpages for these interfaces, or do we
assume that only godlike people can use them anyway? I am willing to
write manpages for them.

They already exist, but they really are only used to implement
higher-level
primitives like locks and condition variables. The rest of the kernel
should
use the higher-level primitives anyway.

Well, really turnstiles don't have manpages, but this is still OK as
they are only used in mutex while the "real" sleeping primitive should
be identified by sleepqueues.

Ah, there is a sleepqueue(9), but not a turnstile(9).
