Change subject: Limit number of rowsets in compaction selection to 32 in TSAN 
mode
......................................................................


Patch Set 1:

The 256K is coming from the fact that the iterators are holding onto a 
BlockDecoder for each column, and the default cfile page size is 256K. So, 
those BlockDecoders that work by decompressing a page at a time up front are 
likely to retain ~256K of memory each.
