    I wouldn't call it convoluted.  The concept is actually quite straight
    forward, its just that the implementation sucks (even the reimplementation
    FreeBSD did), plus many BIOSes are half-broken and don't actually do what
    you tell them to do.  It's a real mess.

    That said, I'm not familiar enough with NetBSD and OpenBSD's interrupt
    handling code to have an opinion.   I have heard some interesting ideas
    regarding how to solve the problem.
