I have not had a crash since applying this patch:

even with INVARIANTS turned off. Nor have I seen an xl0 watchdog
timeout.
I'm going to play with it a bit more before I call it good, but it's
certainly looking better than before.
I'll keep my debugging kernel in place, too, so that I can get a core
dump and symbol table if I see another crash.
I'll keep you all posted.
