Hello,
We added a new parameter to ndb_redis module. If set to 1 a "FLUSHALL" command 
is issued to the REDIS server when reconnecting to a server after a failed 
command. This way for each failed command the database is flushed. 

This is useful when a connection to the REDIS server may become unstable and 
some commands are issued but the replies are not received (it may happen that 
the command has reached the REDIS server but the reply was lost). If for 
example we increment and decrement counters this may leave the db in an invalid 
state.

This can especially happen if the allowed_timeouts/disable_time parameters are 
configured, since the first commands may be issued and the next ones are never 
tried.
