> Having recently spent some time trying to use ThreadDumpHandler to diagnose a 
> "lock leak" i realized there are quite a few bits of info available from the 
> ThreadMXBean/ThreadInfo datastcutures that are not included in the response, 
> and i think we should add them:
> * switch from {{findMonitorDeadlockedThreads()}} to 
> {{findDeadlockedThreads()}} to also detect deadlocks from ownable 
> syncrhonizers (ie: ReintrantLocks)
> * for each thread:
> ** in addition to outputing the current {{getLockName()}} when a thread is 
> blocked/waiting, return info about the lock owner when available.
> *** there's already dead code checking this and then throwing away the info
> ** return the list of all locks (both monitors and ownable synchronizers) 
> held by each thread
