i saw the description in the Adobe presentation, it was one of the case points 
i considered while designing my package.  it seems your system manages the 
much more general case about running Lua code in parallel. I still think the 
best way to get that should be something like LuaThreads, but with a much 
finer mutex handling.  unfortunately, that would mean a very deep analysis of 
the tables and stack handling core.

my package is simpler because it limits what can be done in 'background' code: 
it shouldn't touch the Lua State.  that's enough to write C glue code to 
blocking libraries without freezing the Lua code.
