while 1 instance runs OK

AFAIK long kernel could lead to driver restart if it executed more than 2 seconds under Vista.
No one of kernels in my app took so long. Moreover, I increased driver restart limit via registry to 15 seconds.
Though running 4 copies of app lead to driver restart time to time.
Why brook runtime can do correct scheduling to avoid long driver unavailability to OS watchdog timer?
