Would it make sense to declare the two variables: warmup and cooldown as global 
instead of having them a static members of RubySystem?  If we want to move 
towards 
having multiple ruby systems, I would prefer all static variables in ruby system
be simply made global.


src/mem/ruby/system/System.hh (line 78)

    You are returning the same variable from both the functions.
