The known good kernel (july 4th) just built the world successfully with -j16. I think I'm going to MFI386 Alan's pmap fix to pmap_insert_entry(), that at least seems to help things out quite a bit. I'm building now with an INVARIANTS/WITNESS kernel to see if its perhaps related to the memory-modified-after-free bug that somebody (you?) reported. Drew
