 With the second patch (and the first), things are definitely _more_ 
 stable, though I still get crashes (with, unfortunately, no backtrace 
 info, because the console is garbled) doing a -j 16/-j 24 build on an 
 8-vcpu amazon EC2 instance.  On another dom0 where I was seeing this 
 particular problem, it seems to be gone.
