It also has a problem where it causes lua_close to crash if all I do is require the module. I think this is related to the way the module metatables are left on the stack combined with a call to lua_settop. I haven't dug into exactly what's going but converting to 5.3 style modules is probably a start - if anyone else has done this work please let me know.

luaossl *almost* has windows support.
https://github.com/wahern/luaossl/issues/77
It only takes a couple of small changes to get it to compile on
windows, I just haven't had time to figure out how to make it mergable
for a cross-platform release.
