U4-4931 - 6.2 - lock contention & potential application lockdown

See details in issue tracker, this is #384 and #388 re-targeted for 6.2(.2).
Is this better than a normal lock statement ? i.e. is using Threading.Monitor.Enter/Exit any different than a normal c# lock?

Just wondering since wring using (new MonitorLock(...) { } is actually slightly more typing than a standard c# lock ;)
