[ handling user commands event-drivenly ]

&gt; The summary we arrived at last time was that by default user
&gt; commands should be executed strictly sequentially.  This was to be
&gt; done via sequence number dependancies.  However, we also saw a use
&gt; in commands which were to be explicity executed in parrallel with
&gt; other user commands.  One of the primary uses for such was an
&gt; interrupt command which more or less said, "kill the entire command
&gt; queue NOW!".

Yep.  The posts leading to this one sparked my thinking that if the
events were posted by the same object, execute them sequentially:  a
generalization of the above player-command case.  Is such a
generalization necessary?  The above case could be implemented in the
player object itself, queuing things and doling them out as
appropriate, rather than in the event-handling systems where the
generalization would be done.

One could use a sort of "super" event that is responsible for the
execution of a series of sub-events, and successful commit of the
super would occur when all the subs themselves committed. 
Unfortunately, the potential for involving a large(r) number of
objects in that super event could cause a lot of failed commits until
this super event drove the thing to single-threading.

&gt; (Hey Jon!  This is another thread to add your list of things to dig up
&gt; -- the one about command sequencing, priority commands, command
&gt; interrupts, and job control for asynchronous command execution.  It
&gt; was mainly between CG and myself.).

I'd certainly appreciate a look at it.
