Deferring a function call

For me nothing beats using twisted ( http://www.twistedmatrix.com ) with 
its clean implementation of deferreds and a host of other useful things 
for simulations besides being the 'Swiss Army Knife' of networking in 
Python. If you throw in stackless ( http://www.stackless.com ) 
simulations with extremely high counts of participants and/or fine 
granularity distributed across multiple machines are fun to write, 
operate and maintain.
