Change subject: KUDU-2653: suppress krb5 memory leak found on Debian 8
......................................................................
Patch Set 2:

DoSaslInit) but then the leaks just cropped up elsewhere. Posting a full stack
trace for posterity:
Direct leak of 16 byte(s) in 1 object(s) allocated from:
