To further clarify: Job A takes 30 minutes and job B another 30 minutes. 
They tie up both agents for the first 15 minutes for no reason. Now B 
depends on A (A uploads artifacts to a Nexus that B uses). So the truth is 
that I don't really mind if they run on the same agent or not (B will find 
A's output no matter what). What I really want is for B not to tie up an 
agent while it is waiting on A...
