History
Bruce Evans 05b2c96fd3 Detect interrupt storms better. The storm detection didn't work at all 
with an ASUS A7N8X-E motherboard in APIC mode, since storming interrupts
don't repeat immediately.  Use DELAY(1) to wait a bit for them to repeat.
This affects all systems.  Only delay for the first
(10 * intr_storm_threshold) interrupts (per interrupt handler) so that
this is only a pessimization while warming up.  Throttle after calling
the sub-handlers instead of before so that the long delay given by
throttling can be used instead of the DELAY(1) to detect storms after
warming up.

Reduced the throttling period from 1/10 second to 1/hz seconds so that
throttling doesn't destroy performance so much.  Interrupts that are
detected as storming are effectively handled by polling at a frequency
of hz Hz.  On A7N8X-E's there is another hardware or configuration bug
that makes the throttled frequency closer to 2*hz Hz.
