Matteo Bertozzi updated HBASE-15144:
------------------------------------
    Attachment: HBASE-15144-v4.patch

attached v4, I changed a bunch of things to fix a problem where the wal size 
was always displaying 0, and I tried to remove some of the extra allocation of 
all the CircularBuffers (but this can be optimized further). 
What do you think? if it is good for you I'll commit that. if you have other 
changes/improvements feel free to post another patch
