[Haskell-cafe] pool, persistent, persistent-sqlite: Space leak

Hello Michael, hello fellow Haskellers, there seems to be a space leak in either 'pool', 'persistent' or 'persistent-sqlite'. From the behaviour I suspect the bug to be in 'pool'. When I run a transaction in an infinite loop, my program keeps eating more and more memory, even if the transaction itself doesn't do anything: forever $ runSqlPool (return ()) pool This doesn't happen for non-pooled connections, i.e. the following code runs in constant space as expected: forever $ runSqlConn (return ()) conn Versions are pool-0.0.1, persistent-0.4.2, persistent-sqlite-0.4.0. It happens for both file and in-memory databases. Greets, Ertugrul -- nightmare = unsafePerformIO (getWrongWife >>= sex) http://ertes.de/
