   I don't get that. Does NetBSD handle interrupts in a way totally different 
   from BSD?

What I meant when I said that to Kamil is that we don't have any
formalized notion called `top half' and `bottom half'.  We have hard
interrupt handlers which are supposed to have small bounded latency,
and we have soft interrupt handlers and kernel threads at lower
priorities to which hard interrupt handlers defer long computations
and I/O.
