Uwe Schindler commented on LUCENE-3659:
---------------------------------------

Robert: That was the first idea that came to my mind, too. I think thats a good 
idea. It especially strange that the segments_xx file (which is not part of the 
current segment) is written with MERGE/FLUSH context. It should be written with 
a standard context? Or do I miss something? (This was the reason why I added 
the file name check). Initially I was expecting that writing the commit is done 
with a separate IOContext, but it isn't - the noisy debugging helps.
