triggered by starting a linux binary (ICAclient), the netbsd-5 system 
dropped to single-user, fsck(8) dying with the following wapbl assertion 
failure:

I've seen this problem three times so far. The only way out appears to 
be a 'tunefs -l 0 /dev/rwd0[aefg...]' followed by 'mount -a'.

"Known issue", or should I send-pr?
