There's no requirement to do so in eCos (hence the "count" argument to a
DSR). But if an interrupt is just saying "something's happened", it's
easier to mask it and process every event in the DSR once, than keep
getting the ISR again and again when all it's doing is delaying execution
of the DSR. Basically it depends on the requirements of the device.
