* DESCRIPTION
* This structure defines the transaction manager.
* It holds a qlist and a qmap, a lock on the transaction manager, and
* a timer used for the list.
* The manager is responsible for keeping track of every request mad that was
* sent. It is used for finding mads according to their transaction id, and for
* acting as an event wheel - reporting as error each packet was supposed to get
* a response and didn't get one by the timeout time expected.
*
* Both the list and the map hold the osm_madw_req_t objects - one for every madw.
*
* Managing of the list:
* The timer wakes on the timeout of the first madw. If the waking_time is greater than
* the current time - then the mad received a response. If not - the mad didn't get
* its response.
*
