CommitFest dragging?

Folks,

It's been 3 weeks since the start of the commitfest, and less than half 
the patches have been committed or sent back.  We seem to be stalled. 
What's going on?

Looking at the wiki, I see some issues:

Robert Lor, Jaime Casanova, Mark Woodward, Heikki Linnakangas  Zoltan 
Boszormenyi and Greg Stark apparently haven't responded to issues raised 
by their reviewers.

David Fetter, Stephen Frost, Greg Stark, Thomas Lee, Bruce Momjian, 
Peter Eisentraut, Pavan Deolasee, Martin Zaun and Simon Riggs are all 
"reviewing" patches and need to report back, either sending back the 
patch or finishing it.

And there's four patches which aren't even being reviewed because most 
of the reviewers are stalled (not) reviewing other patches.

So, what do we need to do to get this moving?
