I don't see any problems. =)

@snoyberg, why do we use `atomicModifyIORef` in `Control.Monad.Trans.Resource`? I mean, there's lots of code on conduit that just reads a reference, does something and then writes back something other on the reference, so it's not like there's something that depends on the atomicity of `modifyRef`. Not using atomic operation could shave some overhead on multicore systems.
