Major bummer. The trick I used to run parrallel queries to madison is fairly 
broken.

Fixing this properly will require to change all Config::Model code to make it 
asynchronous. (using Future or Promises). This is a huge work :-(

The alternative is to remove the asynchronous stuff and to run the 
queries to madison in a blocking mode. But running these queries is quite 
long as soon as you have a lot of dependencies (~ 1s per dependency). 
The caching mechanism helps a bit but it's not a silver bullet.

I'm still stratching my head ...
