Your problem in all of this is going to be convincing folks that this is
a problem worth solving.  I'd start this off with something
attention-grabbing.

Two things.  Good, snazzy writing doesn't repeat words.  You repeated
"interrupt" twice in that first sentence.  It also doesn't get my
attention.  Here's a more concise way of saying it, and also adding
something to get the reader's attention:

	User Interrupts directly deliver events to user space and are
	10x faster than the closest alternative.
