Well, why am I seeing a regular lock() request in the queue then (see 
the first queue element below)?

   queue:
                 L(writelock/regular/instance_2_1/,40388::373)
                 TL(writelock/regular/instance_2_1/,45507::413,20000)

The  first queued lock request is clearly a Request for a lock() , *not* 
a tryLock()!
