Crashes due to cross-thread race conditions

Key: TS-3797

Project: Traffic Server
Issue Type: Bug
Affects Versions: 5.3.0
Reporter: Susan Hinrichs

Fix For: 6.1.0
We had seen crashes with the following stack trace occasionally, but
recently we have found an environment where these crashes happen so
frequently that running ATS with global session pools is not feasible.
