when we set `PROC_NOCHLDINIT` on the consumer workers, the module cannot bind to the presentity table. Perhaps @miconda would know why this is the case, but this is the error:
``` ERROR: <core> [db.c:452]: db_use_table(): invalid parameter value [presentity] ERROR: nsq [nsq_pua.c:146]: nsq_pua_update_presentity(): unsuccessful use_table [presentity] ERROR: <core> [db.c:452]: db_use_table(): invalid parameter value [active_watchers] ERROR: presence [notify.c:1034]: get_subs_db(): in use_table ERROR: presence [notify.c:1227]: get_subs_dialog(): getting dialogs from database ```
