Yes.

Running windowed Flash within the content process itself would mean giving
that content process access to the main window's HWND. That's not really an
option for sandboxing, AIUI. Also, running windowed Flash within the
content process would not work with multiple content processes, AIUI. Also,
running Flash in the same process as content sucks more than running it in
its own process.

The best option for "proper" support of Flash would probably be a Flash
process hanging off the master process, with content processes granted
channels to the Flash process via IPDL trickery, plus some extra work to
have the content process tell the master process how to position and clip
each Flash window. It's going to be complex.
