lsof hangs with latest 13.0-CURRENT snapshot

After upgrading from FreeBSD-13.0-CURRENT-amd64-20190328-r345620 to
FreeBSD-13.0-CURRENT-amd64-20190404-r345863, lsof (4.92 from packages)
hangs.

This is true for bare metal installs and virtual machine installs.

How to recreate:

	Install FreeBSD-13.0-CURRENT-amd64-20190404-r345863 snapshot.

	as root: lsof /sbin/init

By running command with -b option, this error is displayed:

lsof: status error on /sbin/init: Resource temporarily unavailable

The return code is 1.

This probably requires adjustment to lsof, but only the FreeBSD
snapshot changed, so I'll start here.

Thanks.

David Boyd.
