Lanes locks around calls to 'require' so that only one can be done at a time. This is essentially all support a multithreading library can give to a module, I think. Using a leaking module would anyways be on the responsibility of the module author and/or user, but if there's something Lanes could do about this, please suggest. We can recycle states but I wouldn't start relying on such behaviour. In fact, I think Lanes suits and was designed for other kind of applications than daemons. They often have a limited scope of what they're doing (compared to, say, a GUI application) and would do better with a cache table of preset states. Lanes is for usage where one would not like to touch anything on the C side.

Another issue which I don't see people mentioning is
how to properly clean up these lua states. My
experience with 'rings' is that for certain third
party modules(say the luasql.mysql binding), it is
impossible to properly clean up a lua state(memory
leaks). So both lua lane and luatask if used in the
erlang manner(repetitively create and destroy states
like function calls), would have issues for writing
daemon process.
