* @title: GdaLockable
* @stability: Stable
* @see_also: #GdaMutex and #GMutex
*
* This interface is implemented by objects which are thread safe (ie. can be used by several threads at
* the same time). Before using an object from a thread, one has to call gda_lockable_lock() or
* gda_lockable_trylock() and call gda_lockable_unlock() when the object is not used anymore.
