Probably more changes than needs to be in one patch:
- use hooks for:
-- wombat_open - called by create_vm
+1 Perfect!
-- wombat_request - called instead of apw_request_push
I would like to maintain a function which is analogous to
lua_pushstring() and lua_pushinteger() for pushing the request_rec
into a function call or whatnot from the C side.
Will this work with the hook? (I am a hook newb).
-added apr_lua.c and .h - only handles tables for now. Can be
extended to do
more in future.

Even though these are static, we might want to be careful in naming
as these are reaching into lua's namespace (lua_* and luaL_*).

Why pass the pool in (other than matching the hook form, but this
isn't invoked via ) and what is the general policy on borrowing from
the apr namespace for an exported function?
