The definitive answer from Wes Peters--he forgot to include
freebsd-questions on the cc: line, so here it is. I put his
name in the "From" line.

% If you're not doing any 'make world's, then /usr/obj is destroyable.

As the name implies, /usr/obj is a place where the intermediate object
files that make up the commands, utilities, etc. are placed. If you
change 10% of the system source between 'make world' commands, you only
need to regenerate 10% of the object files, the rest remain untouched.
If you remove /usr/obj, you will have to remake 100% of the object
files, at a cost of extra computing cycles, disk I/Os, etc.
In short: if you've got the disk space and are going to be rebuilding
the world, leave 'em. If you need the disk space, grab it. If you're
undecided, buy a Jaz drive and a cartrige for /usr/obj. ;^)
