(1) I can run the ipsec tests in a fresh VM in isolation and they finish
within 30s. That alone should be a good indicator that the problem with
those tests is not actually the commit here.

(2) We have a very long history of various rump-based tests timing out
in one environment and working in another and noone ever bothered to fix
that. A common example is the quota test cases.

(3) We have a persistent history of RUMP stuff failing because ATF
doesn't properly cleanup behind failures. E.g. left-over rump_server
instances breaking random other tests.

All in all, there is literally no indication here that the l_lid change
has any problem. At most we have some indication that it changes some
timing and that in turns (re)exposes RUMP bugs. So no, I'm not willing
to revert a commit based on such shady evidence.
