Pretty darn big. It causes an exception and all of the overhead associated 
with exception handling PER INSTRUCTION. I think that's why -current is 
painfully slow on the m68060s, although I didn't have enough patience to 
wait for a full boot to see if that was really it.

On the other hand, after recompiling the whole OS with -m68060, the 
performance should be as good as, or better, than with older NetBSD, and 
MUCH better than the daily NetBSD 3 binaries.

An mvme177 should be pretty quick with NetBSD...
