Description

just a few tests that illustrate the issue:
tokudb.rpl.rpl_tokudb_row_img_blobs 'row'

There are a several of these in quicklz.cc. Reporting them all here because they can probably all be fixed at the same time. If something needs different treatment it can be broken out into a new issue later.
