Andres de la Peña commented on CASSANDRA-17240:
-----------------------------------------------
{quote}The flakes in the memtable size test are now fixed. [~adelapena], you
can rerun the above if you wish; I have already run both flaky ones,
{{MemtableSizeOffheapObjectsTest}} and {{{}MemtableSizeOffheapBuffersTest{}}},
thousands of times.

CASSANDRA-17939 has just been merged. It will create conflicts with the new job
for tries that this patch adds. The changes on CircleCI config should be
adapted to also add an associated job for repeatedly run any new, modified or
manually specify unit tests with memtable tries. [The previously mentioned
commit|https://github.com/adelapena/cassandra/commit/23fe8743f185ad1b93cce37383d6d4807ea14e36]
does exactly that. It was meant to help with the rebase pains.
