Sorry it's taken me a while to reply to this; ironically, most of my time
has been spent on freebsd-doc recently.

I've just spent five minutes trying to phrase a reply to this that manages
to convey my complete disagreement without resorting to profanity.

You're talking bollocks.

Sorry, I failed.  I'm the lesser man for it, I know, and I can only pledge 
to widen my reading (or buy a set of Shakesperean Insult Fridge Magnets)
so that it doesn't happen again.

And it keeps the skilled people away.

You have two systems, one documented, one not.  You're looking for something
to work on, but don't have a great deal of free time to spend.

Which one do you work on?

Matthew Dillon, a FreeBSD contributor who has been improving FreeBSD's
virtual memory subsystem, NFS implementation, and various other bits and
pieces, recently said (in <199906262123.OAA04029@apollo.backplane.com>
on the committers@freebsd.org mailing list)

    [...]

    I guessed I freaked some people out when I declared that I wanted to 
    work on the VM system, discussions in the first few months went with 
    half of core talking to me like I didn't know jack when I do know at 
    least jack, but had to come up to speed on FreeBSDisms in the code 
    and the utter lack of documentation.

    [...]

That quote is from part of a message on another topic (and one which is
off-topic for -hackers).  

Matt's a very talented coder.  But he still has to come up to speed on how
things have been done on the FreeBSD project, and how we've diverged from
published documentation (such as "The Design and Implementation") before 
he can do useful work.

In this respect, Matt's one of the good guys.  Not only has he done some
sterling coding, but he's also taken the time to contribute documentation
explaining not only what he's done, but also what other code in FreeBSD
does, and more importantly, *why it does it that way*.
