I have been following this thread with interest, and I remember it  
quite differently to your description. What I saw was one mail from  
Rickard Green saying that the issue would be fixed in a future  
release, and a number of other people offering workarounds until that  
time, along with their experiences. I was rather heartened by this.

See above.
