Comment(by basvandijk):

 Replying to [comment:3 simonmar]:
 > Applied, thanks!  I've also bumped the version of the stm package to
 2.2.0.0 since `catchSTM`'s type has changed, and I'll upload a new version
 to Hackage.

 Thanks.

 The new stm
 [http://hackage.haskell.org/packages/archive/stm/2.2.0.0/logs/failure/ghc-6.12
 doesn't build] however because we need to depend on the new base-4.3 which
 will export `throwSTM` from `GHC.Conc`. Sorry for not putting this in the
 patch.
