   but like ... also... @uranusjr, using this example... there actually are 
some reasonable arguments for not serializing the complete task object.  for 
one it's more efficient. why serialize the full task (taken to include the full 
dag and all other tasks) and send over the network just so that "needs 
expansion" can be evaluated on the server, when you can just determine locally 
whether it needs expansion and tell the server what to do and save the net 
traffic and processing time?  further do we not run into recursion problem 
serializing at task that has the full dag when the dag also has all tasks each 
of which has the full dag and on and on.....
