>Description:
After processing a request to a Lua handler it doesn't appear that the Lua state is closed properly. This causes objects which need to be cleaned up by the garbage collector never to be cleaned up.
>How-To-Repeat:
Create a Lua table/object which creates a local domain socket, and which has a garbage collector which closes the socket and removes the corresponding file in the file system.
Instantiate that object in a Lua handler in bozohttpd; make a few connections which cause the objects to be created, and notice all the socket files remain in the file system since their garbage collectors where never called.
>Fix:
Add lua_close(L) after the Lua context is no longer needed for the request.
