Thanks for the observation and the inputs.

Please note that we developers like *everybody* else are limited by the 
number of hours that we can put in a day. We do try our best to address 
the issues that everybody brings across to us. We are definitely 
interested in fixing any kind of problems that GlusterFS does have. We 
do look forward and appreciate your co-operation and patience in making 
it as stable as possible.

As we have been requesting on the mailing aliases, if you encounter an 
issue which you definitely consider is a bug, please file a bug at 
http://bugs.gluster.com. Providing the appropriate volume, log and as 
much a detailed description of the problem would definitely help us move 
forward.
