Hm... I hadn't really noticed that, mostly because w/o
softdeps it takes forever to rm -r a big tree, so it's
still MUCH faster.

MULTIPROCESSOR yes
LOCKDEBUG yes because I wanted to see where the hangs were
          (although since the cont cont trick led to a
           subsequent panic anyway, I'll probably turn off
           LOCKDEBUG again as soon as the locking problem
           is narrowed down, since the proc size difference is
           painful for things like systat(1))
DDB yes but running X
