Lua with existing conservative GC?

[Tom <tmb-lua-l@...>]

Has anybody used Lua in a C/C++ system with a conservative GC?
Is there some way of turning off Lua's garbage collector
entirely?  And are all pointers inside the Lua implementation
visible to a conservative GC?

I would like to use it as an extension language for a C++
system that uses the BDW conservative garbage collector at
http://www.hpl.hp.com/personal/Hans_Boehm/gc/

It seems at redundant and possibly harmful to have
both Lua's own memory management and the GC try to manage
the same memory.

Tom.
