[DGD] priority of user/network i/o vs callouts

[Raymond Jennings]

I remember one time you said you'd refuse any patches that rearranged
things so that callouts were pushed behind user i/o or something.

Did I get that right, and if so...why is dgd's design based on this
relative priority?

My personal choice would be to have interrupts at top priority, then
handling i/o, then callouts, and finally housekeeping.

Why would your opinion be different?

If I misunderstood please say so and disregard the remaineder.
