Let it burn

Since toad gave tacit approval (or at least apathy) here are the two main patches from Frost. Apply and watch the network wither and die, or eat crow and spend months arguing about why it works.  I used the less insane seeming values from mmaalfdks for requeststarter delay reduction... if the network burns to the ground with those values, oo's original values should be far worse.
These are constants and should hence be in upper case and documented.

As I understand it, this implements a restricted low-pass filter on the delays for non-SSK and non-realtime requests. The members may be named accordingly.
