When you have a "preferred" size of 30, the proxies will try to give
you 2^30 key blocks, but may, for whatever reason, give you smaller
blocks (3*2^28 blocks, 2^29 blocks, or 2^28 blocks).  That's why it's
a "preferred", not a "required" size.

Is it possible for you to increase your buffer size?  If you keep
75-100 blocks on hand at any one time, it won't matter what the
distribution of blocks you get is.
