strange as this may seem, one of the best ways to _reduce_ (i.e. not
eliminate) silo overflows is to disable logging of them.

If you get a silo overflow, and log it via syslog and/or kernel
printf(), a large amount of code will be run at spltty(), blocking
more serial interrupts, and likely causing more silo overflows!
