Well, Zaptel needs to service interrupts once every 1000 microseconds.  If
not, it misses a sample (not the end of the world, mind you).  No driver
should leave interrupts disabled for anywhere *near* 1000 microseconds.
If you need that long, put it in a bottom-half handler.

If interrupts are disabled there is nothing we can do, except not
interrupt as frequently, but this leads to additional latency.
