One concern though: can you benchmark ./build.sh on a machine with 8 or
more CPUs? I fear that vcache.lock might be a bit contended and we ought
to figure out how much. If the contention is not significant, it should
be fine for now.
I can do this if you really want, but I doubt it'll make a difference
unless your src and obj trees are spread across multiple different
types of file systems, because currently for ufs, ufs_ihashlock and
ufs_hashlock are just as contended as vcache.lock would be.
