/* This is a redesign of luaproc.  The design goals and notes -
 *
 * Use eina lists instead of the rolled your own lists.
 *   Looks like a FIFO double linked list.
 * Use ecore threads instead of raw pthreads.
 *   Ecore threads pretty much wraps pthreads on posix, but has Windows support to.
 * In general use EFL where it is useful.
 * One fixed unique message channel per script.
 *   Probably one fixed unique message channel per object, which each script in the object shares.
 *   But might be better to handle that C side anyway.
 * FIFO queue on message channels, seems the C socket queue is not enough.
 *   On the other hand, could just peel messages the socket queue, then shove them on the scripts queue.
 * Better integration with LuaSL.
 *   Merge the luaproc structure with the script structure.
 * Merge in the edje Lua code, and keep an eye on that, coz we might want to actually add this to edje Lua in the future.
 * Use my coding standards, or EFL ones.  Pffft.
