I think it was achieved, althought there's no automated testcase
nor usage pattern showing it clearly. An example of such usage
would be the implementation of a windowed NPAPI plugin which would
also solve many navigation issues. A simpler one would be allowing
the specification of multiple input files from the commandline and
playing them all at once (or serially, with an option).

To be honest I don't remember VM re-entrancy being a requirement
for AVM2. Was probably mentioned as a requirement for the windowless
plugin (to avoid having to spawn a new process for each page object).

For AVM2 (if that's required for lumosity.com) you could start
by looking at lightspark, which does _only_ AVM2 and supports
Gnash as a fallback for AVM1 apps. Making lightspark embeddable
in Gnash could also be an interesting idea, to do the reverse.
