Charm++ parallel programming system

["Kale, Laxmikant V" <kale AT illinois.edu>]

I haven't looked at CentralLB:MigrationsDone, but I think a simple use of
a future (or just a flag) can make it so that the user just has to make a
blocking call to wait for the event. Am I missing something?

I will be happy to look at the code,and discuss, ma be with Celso and you
on skype with the code in front of us.
