Comment on attachment 62898 [details] Errk, better patch I think this would be more readable if the #ifs were moved exclusively inside the commit and decommit functions. This won't compile because you've left the argument names out even though you are using them in decommit.
Created attachment 62908 [details] Even better patch!
