 embedding a manifest in flashproxy-client and obfsproxy? That's the next
 thing I'd try. Then you have to test it some way that doesn't involve
 running it from the command line (like building a wrapper that sets
 environment variables and runs obfs-flash-client).

 obfsproxy.exe, and there was no change. I thought that maybe "Start Tor
 Browser.exe", vidalia.exe, and tor.exe might also need to have manifests,
 but I didn't know how to do that. I tried going into their properties, and
 put them in "Windows 7" compatibility mode, but nothing changed.

 need to have tor.exe start the PT with the `CREATE_BREAKAWAY_FROM_JOB`
 (`0x01000000`) flag. I do this in `subproc.py`, and the underlying reason
 is the same, explained in detail

 (`0x00000200`) for good karma, but I don't think it's necessary.)

 Sweet, good find. I'll give this a try tonight.
