-z was the trick. (I've never used nstat before.)

pannekake:~> nstat -z | egrep '(TcpExtOutOfWindowIcmps|Icmp6InErrors|TcpExtTCPMinTTLDrop|TcpExtListenDrops)'              
Icmp6InErrors                   0                  0.0
TcpExtOutOfWindowIcmps          4                  0.0
TcpExtListenDrops               0                  0.0
TcpExtTCPMinTTLDrop             0                  0.0

Next time it triggers, I'll see if TcpExtOutOfWindowIcmps increases, then.
