    Affects Versions: 2.0.0, 0.98.10, 1.1.0

We have a cluster which is optimized for random reads.  Thus we have a large 
block cache and a small memstore.  Currently our heap is 20GB and we wanted to 
configure the memstore to take 4% or 800MB.  Right now the minimum memstore 
size is 5%.  What do you guys think about reducing the minimum size to 1%?  
Suppose we log a warning if the memstore is below 5% but allow it?

What do you folks think?
