CVE-2020-12658

gssproxy (aka gss-proxy) before 0.8.3 does not unlock condmutex before pthread exit in gpworkermain() in gpworkers.c. NOTE: An upstream comment states "We are already on a shutdown path when running the code in question, so a DoS there doesn't make any sense, and there has been no additional information provided us (as upstream) to indicate why this would be a problem.
