RACE CONDITION IN AFR:
----------------------
* Who is affected?
If you are using AFR in a multi-user environment and your applications
are writing to common files without locks, there is a possibility
CORRUPTION.

GlusterFS is expected to write atomically across replicated volumes
when the files are opened with O_APPEND mode, irrespective of locks.
Fix in works will ensure all writes to be atomic always. We will
make an announcement shortly.

Thanks to Gordan Bobic and Martin Fick for identifying this bug.
