I noticed that when running the test suite, there would be a file server/log1.txt left. This file is created by one of the config reload test. Running this test individually was doing the proper cleanup. I noticed that the Signal test that was checking that files could be rotated was causing this side effect. It turns out that none of the config reload tests were disabling the signal handler (NoSigs=true), and since the go routine would be left running, running the TestSignalToReOpenLogFile() test would interact with an already finished test. I put a thread dump in handleSignals() to track all tests that were causing this function to start the go routine because NoSigs was not set to true. I fixed all those tests. At this time, there are only 2 tests that need to start the signal handler. I have also fixed the code so that the signal handler routine select on a server quitCh that is closed on shutdown so that this go routine exit and is waiting on using the grWG wait group.
