nspluginwrapper (was Re: linux-f10-flashplugin11 not works for 9-stable (Linuxulator?))

[Andrey Chernov]

It seems part of the bug is already noticed by maintainer (Jung-uk Kim) but 
nothing is done to fix it:
http://lists.freebsd.org/pipermail/freebsd-stable/2011-September/064067.html
BTW, the bug is in native FreeBSD code (rpc.c), not in linux code.

Jung-uk, could you fix/hack it somehow, please?
