   This patch depends on what the scans or reads does with the blocks till the 
configured size. Just for understanding or initial review I have based this on 
the pread size (which is 4 * block size). This needs a better measure may be 
based on the number of blocks purely rather than the block size. But the idea 
is that if based on that config we find that the seekOrSkipToNextcol() has 
always landed in the immediate next block always go with next() rather than 
this seekToSkiptoNextcol(). In our tests it is revealed that the comparison 
that we do here in case of ensuring whether to seek or skipping is adding to 
the performance rather than the actual seek.
