[DGD] call_outs

[Steve Wooster]

     Yet another question occurred to me... I've heard that if you do a 
call_out for 3 seconds, and one for 5, the 3 second call_out is guaranteed 
to execute before the 5 second one... What about if you do a 5 second 
call_out, and a bunch of chained 0-second call_outs... Is there any 
guarantee that the 5 second call_out will be executed after the last 0 
second one? (or is it only guaranteed to execute after the first 0 second 
call_out?) Thanks!
