[Haskell-cafe] Memory leak in streaming parser

I refactored the code and uploaded a new version to Hackage (YamlReference-0.2). It is cleaner now and much more efficient. It is still "leaking" memory though. The profiler hints at "bindReply" as the culprit retaining State and Reply objects, but it isn't clear to me why the code would do that. Trying to `seq` things again either kills streaming or has no effect. Perhaps my basic approach is wrong... Any advice would be appreciated, Oren Ben-Kiki
