Ok, it's pretty stable now!  I only tried on an SMP kernel running
on VMware, but at least several runs of the following tests can't
crash HAMMER anymore:
 - blogbench -d /mnt/HAMMER
 - cpdup /usr/pkgsrc/. /mnt/HAMMER/.

The only thing I noticed was messages like below appeared all
over the console:
  Warning: vfsync_bp skipping dirty buffer 0xc13ab924

but I see this one on a UFS filesystem too, so I think I don't need to
worry much about it.
