Subject: [PATCH 112/128] write-behind: Allow trickling-writes to be
configurable
This is the undisputed/trivial part of Shreyas' patch
he attached to https://bugzilla.redhat.com/1364740 (of
which the current bug is a clone).
We need more evaluation for the page_size and window_size
bits before taking them on.
