Ouch, all the above were -mips4, we need to use -mips3 since we need to
Run on Indys/Indigo^2s etc.

19.328u 48.854s 1:49.01 62.5% 0+0k 867+705io 0pf+0w

Ratios 1.86 vs. 1.85:
	user time:   53% slower
	system time: 64% slower

dbhash alone:
	% time ./dbtest86 hash t2hash.inp > /dev/null
	0.023u 0.121s 0:00.22 63.6% 0+0k 3+4io 0pf+0w

	% time ./dbtest85 hash t2hash.inp > /dev/null
	0.008u 0.012s 0:00.01 100.0% 0+0k 5+0io 0pf+0w

So user time is 3x slower, system time is 10x slower.
I see no difference in dbtree times, only in dbhash times.

The speed difference in recno is big as well:
	% time ./dbtest86 recno t4recno.inp > /dev/null
	0.243u 6.682s 0:06.97 99.2% 0+0k 0+0io 0pf+0w

	% time ./dbtest85 recno t4recno.inp > /dev/null
	0.175u 0.635s 0:00.81 98.7% 0+0k 0+0io 0pf+0w

recno 1.86 is 38% slower in user times and again over 10x
slower in system time.
