I am pretty much in support of your approach, at least at the build file
level. I'm still thinking about the desirability of nested tasks. Actually I
was going to try and get some multithreading based on async attributes into
1.3 but I held off because of your patch. That may be a little ironic.

Agreed. I think the threading structure should be mirrored in the build file

Don't consider it a dead topic. Please submit your ideas to the Ant2 process
(I will anyway, if you don't :-) )
