charles hannum has recently found and fixed some problems
i introduced when adding the fix to vm_object_collapse()
from niklas hallqvist.  please make sure that these files
have these versions before reporting any more problems
with machine hangs, and stuck processes, lpd hanging, etc.

these are the files you need to check, in src/sys/vm:
