stm-io-hooks: STM with IO hooks

This library provides a Software Transactional Memory (STM) monad with commit and retry IO hooks. A retry-action is run (at least once) if the transaction retries, while commit-actions are executed iff the transaction commits. The AdvSTM monad also gives some atomicity guarantees for commit-actions:

• When a TVar is modified in a transaction and this transaction commits, the update remains invisible to other threads until the corresponding onCommit action is run.

• If the onCommit action throws an exception, the original values of the modified TVars are restored.

Note: The package can be used as a drop-in replacement for Control.Concurrent.STM.

Feedback is welcome!
