Right. This doesn't work because of the way the LD_LIBRARY_PATH is
constructed in the opera shell script. The native_threads path will go
first, meaning the green_threads libraries don't get loaded. My bad.

Ok. So if I edit /usr/X11R6/bin/opera and s/native_threads/green_threads/
it gets a bit further. However now I get problems with other symbols
which the plugin assumes are available because you're using it in Mozilla
or a derivative, right? Wrong. So, I hacked the plugin build to link
in different Mozilla libraries until all the symbols were resolved, and
now Opera is segfaulting :(. At least its leaving a core, but none of
this is very promising for getting things working under Opera.
