Different lua pthread (or other threading) interfaces?

["Mike Panetta" <panetta.mike@...>]

I have found the lua51pthread 'module' and it seems great, but its only
one way to do this sort of thing, and it requires intrusion into the
lua core, so its not really a module in that sense.  Has anyone
else written or found a threading implimentation that they
like/dislike?  I wanted to look at the different ways people are
doing this.  I have the beginings of an idea of my own that would
not require modification of the core, and thus could be a pure module.

On that note, is it possible to put an index table on the global
table?  I would use this to hook mutexes to 'global' variables by
calling a cfunction that would index into the real global table in its
own thread (probably the main thread) and locking the mutex during
access.  Basicly all lua 'threads' would be technically isolated
from each other except for this controlled access.  Other local
variables could be 'marked' as thread variables if you wanted to pass
them between threads, for instance during thread instantiation.

Does this even sound like a possibility?

Thanks,
Mike
