r13237 | Verify that pending changesets are seen by pretxn* hooks but not by other | ||
processes that access the destination repo while the hooks are running. | ||||
The hooks (python and external) both reject changesets after some think time, | ||||
during which another process runs pull. Each hook creates a file ('notify') to | ||||
indicate to the controlling process that it is running; the process removes the | ||||
file to indicate the hook can terminate. | ||||
