Tuning Streams

[Lance C Norskog]

Ummmmm, I just remembered something.  The reason you see lots of time
charged to the splx() kernel routine is because kernel profiling is
very screwy in regards to interrupts, and all time spent in device 
interrupts is 'adjusted' (in a peculiar way) right after the splx()
routine drops interrupts to 0.  It's not really spending all that time
fiddling the PIC's.
