I plan to attack this in mid May unless Luke or others get there
first.  As I have mentioned before, making the R engine reentrant
and/or thread-safe will probably not be all that is needed for your
purposes, and fixing the packages, especially those with native (C,
C++ & Fortran) code is also necessary. That is why I have been working
on a tool that aids in the task of removing the global variables.

Also, it may be prudent to prioritize an adequate security model in
your application over allowing concurrent intrusions :-)
