I ran into this crash (I think*) yesterday too, albeit in a (amd64) VM  
with 768MB RAM.
However, I had set arc_min="30M" and arc_max="100M" so I expected it  
to work, but
it crashed within 10-15 minutes of make -j4 buildworld. I changed the  
values to 5 and 30M,
and so far (~30 minutes) no crash. The sources were from late May  
21st, currently building
rev. 192805 (since 192808 broke the build, at least on the tinderbox).

* "I think" because I went to check on it it the middle of the night,  
saw a page fault in kernel mode
or whatever, and figured "damnit... well, I'll suspend the VM, turn  
the laptop off and check in the morning".
I hit shutdown instead, so no backtrace or anything. D'oh!

Thomas
