One more data point:
Depending on the implementation, Lua coroutines need around 1200 bytes
(Lua 5.1 on amd64) or 450 bytes (LuaJIT on amd64). Lua coroutines
share a heap and are roughly equivalent to explicitly scheduled
threads (sometimes called one-shot continuations), but unlike threads,
they (and their stacks) are not automatically part of the heap's root
set.
Footprint for a totally independent Lua environment (called "state")
is somewhat larger. There is no cross-state sharing, so all data
structures (such as module tables) and Lua code has to be loaded into
each state individually, further increasing the footprint.
