I still have the buildworld output from the failure, but given what 
went before I'm not at all confident it represents anything to do
with FreeBSD.

Apart from the buildworld log, no. I was quite surprised at the
lockup, -j3 and a gig of swap had been working fine for several
build/install cycles. It was especially surprising when nothing
turned up on the console.

Make cleandir was run twice and -j2 meta-mode buildworld restarted.  
I'll be more careful with the wreckage next time.

Thanks for writing!
