Comment:

 I agree; something like this is sorely needed, so that users can take
 control of what to do if the transaction starves.

 Curiously I was talking to [http://www.cs.rochester.edu/u/ryates/ Ryan
 Yates] about this very thing at ICFP last week.  He's been doing work on
 GHC's STM implementation, and perhaps this retry-handler thing could form
 part of it?
