    Run `make reset-gcov` after the script target in Travis CI is done.
    
    This should ensure that GCDA files are never entering the cache of
    Travis CI.

+  o Minor bugfix (continuous integration):
+    - Reset coverage state on disk after Travis CI has finished. This is being
+      done to prevent future gcda file merge errors which causes the test suite
+      for the process subsystem to fail. Fixes bug 29036; bugfix on 0.4.0.1-alpha.
