I believe i am seeing activity related to this PR

We're finding that npm gets stuck in updates, and if the parent is=20
killed, it leaves a process in uninterruptible state

(this has not even been killlable during shutdown and a previous box=20
with same symptoms has needed a hard reset)

Child processes get stuck in a DN state, it does not seem to matter if npm =
or
node was running prior to update,  as npm is called as part of the update
process.

This also seems to be affecting separate periodic scripts such as 100.check=
suid
which also become stuck.

We now have 5 boxes in this state, and i suspect all will need a hard reboo=
t to
clear.

Systems are FreeBSD 10.3-REL on ZFS
