Well, I just inserted just over 2 million rows and it hung again:

twe0: status   57007320<CQEMPTY,UCREADY,RQEMPTY,>
twe0:           current  max
twe0: free      0099     0100
twe0: ready     0000     0000
twe0: busy      0001     0100
twe0: complete  0000     0012
twe0: bioq      0000     0023
twe0: AEN queue head 1  tail 0
twed: total bio count in 1950330  out 1950329

And St. Cloud State beat the University of North Dakota in overtime to
win the WCHA tournament. Sigh.

I think I'll turn off softupdates and also run MySQL in a stock
configuration, just to make sure it'll still break.
