client.drsyms-test module load event called twice for appdll loaded by LoadLibrary on Vista

_From [rnk@google.com](https://code.google.com/u/rnk@google.com/) on March 11, 2012 11:32:32_

The test was failing because the output from the event callback was being printed twice. I ssh'd to the bot and had it print the path to the dll that was being loaded, and got this:

92: finished unmangling.

Is this a known issue? If so I was unable to find anything filed in the tracker.
