At the time, two builds were running, 5-i386 and 6-i386, manually  
launched with 'tc tinderbuild ... -nullfs' in separate xterms.

I have HOST_WORKDIR set to /local/work, so the builds will have been  
under /local/work/builds/<buildname> -- I also tried without (/tbox is  
also a local filesystem on this machine), with the same effect.

The interesting issue is that it doesn't happen consistently -- ie:  
most ports got built without these weird errors (I was building x11/ 
gnome2-lite at the time).  Looks like some kind of race condition  
somewhere.

Doing builds one at a time (ie: cycling through {5,6,7,8}-i386) shows  
no errors like this.
