@jeffkaufman "If we could get a pointer to cfg_m"

I looked into that: 
- I tried storing a reference to cfg_m in cfg_s in ps_create_srv_conf, but that won't work as ngx_http_conf_get_module_main_conf returns an invalid pointer during that call.
- To get a cfg_m using nginx api's, we would need a ngx_conf_t or  a ngx_cycle_t, neither of which have during cleanup. 

Should I add a TODO for this?
