you might try 3.1.0a1, esp. if you have a benchmarking rig still
setup and reusable.

it batches replies to DHCPREQUESTs around a single fsync, rather
than keeping it 1:1.  failover is known broken on it ("alpha
quality").  i'm still working on reintegrating failover with the new
fsync changes; i want to get failover performing better while I'm
at it (it always delayed syncs, but it takes 2 seconds to bother
sending bndacks, that sort of thing).
