I'll probably do something close to that.

Actually, I haven't had time to try building a kernel. I was just
estimating the time that the system would stay up before crashing and
guessing that I wouldn't be able to build a kernel in that time. I'll
try removing the memory if I do have problems.

Yeah, I could see that as being bad. Oops. Will do. Thanks.

Funny, I was just wondering and thinking about how source changes were
going to be distributed. I had assumed you guys had already worked out
something with NetBSD; I hadn't looked into it, though. I assume you've
looked at such things as sup, etc.
