arch@ ages ago, with a number of updates I've added for things like
the MAC Framework, locking of SIGIO, sysctl(), timeout(), credentials,
jail, kernel modules, and a few other things. Note particularly large
holes in documentation for file and file descriptor locking, pipe
locking, select locking, process locking, scheduler locking. In fact,
most sections need a lot of work, but I figured it was better to get
this into the documentation tree where people could see/fix it, than
let it rot more. This is not currently hooked up to the build since
it's not yet ready, but can be built easily.
