Investigate using Ward on RTS
While debugging a locking issue a few weeks ago I found myself pining for static analysis tooling. Today I briefly looked at the options and one stood out: Ward. It sits in a very nice point in the design space, allowing the user to define a universe of privileges and annotate functions using standard C attributes.
I think this would be a very helpful tool for describing and checking GHC's locking (and perhaps other) behavior.
