To be fair to julian and softupdates, you can over abuse the -j option :)
I ran on my SMP -current box a make -j50 to compile a kernel and when the
load hit about 21 in top it wedged my box. It didnt like that. I can get
away with -j24 so far havent tried to do any higher but it did NOT like
-j50 :) Didnt run out of swap or anything, just hit a load avg of 21 and
wedged. And I wasnt running softupdates. So I still think there may be a
slight problem or two with the -j option. I just wanted to make sure you
didn't blame the -j problem on softupdates.
