Snapshot of 'native thread'-friendly extension: - call-outs now work, i.e., a Concurrent Haskell thread which makes an external (C) call no longer stop other CH threads dead in their tracks. [More testing and tightening up of invariants reqd, this is just a snapshot]. - separated task handling into sep. module.
