             Summary: Hang in legacy integration tests at shutdown
                 Key: GEODE-8053
                 URL: https://issues.apache.org/jira/browse/GEODE-8053
             Project: Geode
          Issue Type: Bug
          Components: native client
            Reporter: Blake Bender


When we switched the Windows build to release with symbols (RelWithDebInfo), we 
started hitting an apparent race condition at test shutdown that's blocking the 
release. What happens is, apparently:
 * Test case starts running

 * Cache is closed and deleted

 * Stats thread wakes up, and tries to do something with stats

 * Stats code calls a method on DataOutput that attempts to refer to this (now 
dead) cache object

 * Test code crashes due to unhandled exception in stats code

 * Test framework hangs, because it's waiting forever for child process to call 
ExitProcess explicitly (in a nutshell)

We need to ensure that either a) the stats code never attempts to reference a 
dead cache, or b) when we hit the exception in the stats code, we catch it and 
exit gracefully.
