DGD was (originally) designed for the LPmud environment, in which reside
players and wizards whose interests will not always coincide.  Under those
circumstances, neither callouts nor user input can be allowed to starve
eachother.  You may assume that the principle of fairness operates: all
user input and every callout will eventually be dealth with.

However, given DGD's single-threaded nature, it is of course possible to
arbitrarily delay the execution of both, for instance with a host of
bogus callouts.  What you can't do is delay one thing, and not delay
another.
