possible memory leak when taking a snapshot #85

Description

@ami-m

I created a poc with column, it got hit with incoming data for a bout an hour, and after that I ran a loop that created a snapshot of the data once a minute.

I monitored the memory consumption and the memory usage jumped (and was not released) every time a snapshot was taken.

Other than closing the underlying writer, is there anything else I should have released?

if not, then I suspect a memory leak. pprof points the finger at the column.grow and s2.NewWriter as possible culprits.
