I use dynamic-wind for this. If there is something better, I don't know what it is. dynamic-wind is a little bit funny though because if you capture continuations then the in/out handlers can run multiple times which might defy your expectations. You could set up a continuation barrier on the inside to ensure that doesn't happen though.
