If I remember correctly it does nothing for key-requests on the crashed
server. My implementation uses the rest of the available servers to
distribute the keys which were originally destined for the crashed one
for any subsequent request.
Also I added some "features" like chaining several requests together in
one poll(), send(), read() to bring down the number of
systemcalls if setting many key/values at once. It reduces network
latency, thats all.
It's roughly similar to the multi_get, but I solved it on network layer
for set-like commands :)
