/**
 * Indicates that a timeout has occured while attempting to obtain a lock using
 * {@link net.sf.ehcache.concurrent.ReadWriteLockSync#tryLock(net.sf.ehcache.concurrent.LockType, long)}
 * 
 * This is a normal runtime exception which should be handled by calling code.
 * It is possible that simply reattempting to obtain the lock may succeed.
 * Timeouts are often caused by overloaded resources.
 * 
 * The frequency of these Exceptions may be reduced by increasing the timeout
 * if appropriate.
