   > this is outside the surrounding class
   
   who does this ?! :-)
   why not create its own class ? because you will need to add a license at the 
top ? :-)

> Currently we only log the stack trace of the thread that keeps the lock on 
> the page when we can't claim a lock. It is beneficial to set the cause of the 
> CouldNotLockPageException to an exception that shows the stack trace elements 
> of the thread holding the lock.
> This way you can see in the monitoring what was the cause instead of having 
> to go look for the holding (e.g. slow) page in the logs.
