Hm, this series nicely cleans up test_mark.sh failures
but test_tcp.sh now always fails on debug (slow) kernel
builds with:

# TAP version 13
# 1..12
# ok 1 setup network topology
# ok 2 run baseline data traffic
# ok 3 run LAN traffic behind peer1
# ok 4 run iperf throughput
# ok 5 run key rollout
# ok 6 query peers
# ok 7 query missing peer fails
# ok 8 peer lifecycle and key queries
# ok 9 delete peer while traffic
# ok 10 delete stale keys
# ok 11 check timeout behavior
# Checking notifications for peer 3... failed
# 1,9d0
# < {
# < "name": "peer-del-ntf",
# < "msg": {
# < "peer": {
# < "del-reason": "expired",
# < "id": 12
# < }
# < }
# < }
# validate listener output for peer 3: command failed with rc=1: ovpn_compare_ntfs 3
# not ok 12 validate notification output
# # Totals: pass:11 fail:1 xfail:0 xpass:0 skip:0 error:0

Similar failure in test_symmetric_id_tcp.sh

Only the debug kernels tho, non-debug kernels seem to pass.
So probably some race / slowness.

More runs if you want to compare
