Tried that long ago.  As BLK_SIZE is increased the adler32 cost, which 
has to be computed for every offset in the target buffer, increases 
accordingly.  So you end up with both worse compression and more CPU 
usage.

Ah, I was not paying enough attention.  I did not realize
destination scanning was done for every byte.
