Re: on what *L to execute a callback from c

[Rob Hoelz <rob@...>]

Well, if you're using multiple coroutines and are relying on values in
the global Lua environment, you may notice some...interesting behavior
if you aren't consistent with with lua_State you use.  Coroutines may
have a different global environment from one another, so one
coroutine's "print" function may be different from another, or it may
not even exist in a given coroutine.  That is, of course, if you (or
someone else) modifies your coroutines' environments.
