[Haskell-cafe] Tuesday Morning Games (was: Friday Afternoon Play:) The Burrows Wheeler Transformation

[Jason Dagit]

Could we please only change the subject of threads when it's
necessary?  It confuses my mail reader which then confuses me.  Of
course it's not your fault I choose to use an easily confused mail
reader, but at the same time I don't understand the point of changing
the subject of the thread.  And not just this thread; I see it happen
fairly often but this thread seems to have done it a lot in a short
period of time making it a good example.
