I'm seeing some odd behavior if I use load-balance for the pool strategy under 2.4.1.

I'm mining on EMC and Ozcoin.  If I use the default failover pool management strategy, I get a rejection rate of 0.4% or lower with either EMC or Ozcoin as the primary.  If I use load-balance, my rejection rate goes up to around 4 or 5%.  I can see in the logs that, when a longpoll indicates a new block, cgminer will submit 1 or 2 rejected/stale shares for pool 0, and then subsequent pool 0 shares are accepted.  For pool 1, however, cgminer continues to submit stale shares for a couple minutes.  I'm not sure if this is new behavior or not, as I haven't tried to use load-balance prior to 2.4.1.
