* to process the DCB. If there are pending events the DCB will be moved to the
* back of the queue so that other DCB's will have a share of the threads to
* execute events for them.
*
* Including session id to log entries depends on this function. Assumption is
* that when maxscale thread starts processing of an event it processes one
* and only one session until it returns from this function. Session id is
* read to thread's local storage in macro LOGIF_MAYBE(...) and reset back
* to zero just before returning in LOGIF(...) macro.
* Thread local storage (tls_log_info_t) follows thread and is accessed every
* time log is written to particular log.
*
* @param thread_id The thread ID of the calling thread
* @return 0 if no DCB's have been processed
