@hackage stm-io-hooks0.0.1

This library provides an STM monad with commit and retry IO hooks. A retry-action is run (once) if the transaction retries, while commit-actions are executed iff the transaction commits. The library also gives some atomicity guarantees for commit-actions, see documentation for details.

Note: Part of this library uses code from the Haskell Wiki (see http://haskell.org/haskellwiki/?title=New_monads/MonadAdvSTM).
