i'm sure it's a common wish... in fact i was surprised not to find dozens of

i tried to do it with coroutines too (more lightweight), but luaSocket doesn't 
seem to have a truly nonblocking mode.  and i do like it's 'line mode'.

also, even if i think most of the queries could be answered quickly, some of 
them could try to use other blocking libraries (SQL?).  it wouldn't be nice 
to make all queries wait on one.

i'm not fond of sandboxes... and it shows in my code, it's still too easy to 
break the whole thing.

sure... if your send() and receive() functions play nice enough, i'd like to 
do a coroutine based server, and let a handler to fork a thread if it needs 
to use blocking libraries
