Comment (by devel@…):

 Hi Stuart/Daniel.

 Sorry for my extended absence but life tends to always hit hard when the
 timing couldn't be any worse, so you just have to prioritize. :-(

 @Stuart: The corruption was fixed w/ the current TFW when I discovered it.
 I basically isolated the old TFW and the lockless one, put a testing
 environment around it and feeded it all kinds of test data (meaning
 different sizes and such), so I could be sure both worked fine. That's how
 the corruption turned up.

 @Daniel: Don't you worry. I haven't been using the lockless TFW for ages
 now, honestly. It was a nice project that I believed in and it gave me the
 proper opportunity to learn about the inner workings of MythTV. And along
 the way I got to fix a corruption bug. So all in all, it was worth it. :-)
 And you're right, as long as the old TFW does not become a bottle neck or
 otherwise turns out problematic, there is no point in ripping it out and
 replacing it by something else which is entirely new.

 Thanks for everything,
