Hi,

When I got the new driver running I also did some more bonnie runs with the
following drivers: 
2.4.9-pa32 with the old driver and disconnects disbled
2.4.9-pa61 with the new driver and tagged-queueing disabled
HPUX 10.20

I also did one test with putc and getc changed to the unlocked versions
to see what impact the thread safety had. It was large.

I wonder if the lower speed for block I/O with the new driver is due to the
disabled disconnects?

/Daniel
