Comment 0 for bug 954319

To dupe, unzip attatched lists.zip and run

./bin/test -vv --load-list=tmpXctd5i

or similar. Eventually you will start to see hundreds or thousands of tests failing because a readonly.txt marker is not cleaned up. The below are the first obviously related test failures, though an earlier one ( lp.services.webapp.tests.test_dbpolicy.LayerDatabasePolicyTestCase.test_WebServiceRequest_uses_LaunchpadDatabasePolicy fails right before these, for instance) might actually be the/a guilty party.

This can be duplicated outside of the parallel test machinery; it is unrelated.
