Align fractional numbers with integers in debug
Merge branch 'async'
Switch from Text to ByteString for SourceDict

Set cephx username when connecting to Ceph cluster
Set RADOS pool via command line option

Make pool name an optional command line argument, defaulting to
production value of "vaultaire"
Initialize number of real threads automatically

Set the number of capabilities to the number of available processors.

Merge branch 'master' into 'hacky-async-stats'
Use printf to clean up debugging output
