Use AIO to read metadata in 'ddsnap status' #149

GoogleCodeExporter commented 9 years ago

'ddsnap status' can take some minutes to complete because the ddsnap btree
is too large to fit in memory when the volume is large and is aged after
several snapshot deletion. We can use AIO to speed up reading btree from disk.

Chris is working on this now.
