  This patch is essentially does the same thing as __weak_reference one.

  Strange. I've just build native firefox-1.5.0.4,1 from ports, and I can't 
even find info about plugins (menu Help contains only "About Mozilla Firefox",
no "About Plug-ins" there).

  I was curious whether patching rtld _itself_ (w/o using linux-flashplugin7)
hurts your application (i.e. causes a regression). I see that it isn't the 
case. I'm aware that linux-flashplugin7 itself is _not_ stable under
FreeBSD + native browser + linuxpluginwrapper. Patch just makes it possible
to use this combination _if it works for you_ (for many Flash-using sites it
actually works, just not for all).

  As I expected, w/o linux-flashplugin rtld patch doesn't affect operation
of the native firefox: no hangs on www.fifaworldcup.com, no Flash either.
In other words, no regression.
