However, a full minute freeze can be a great evil in many situations -
during such a freeze, the system is completely unresponsive.

So my next question is: How reasonable is the value MAX_RECLAIM_RETRIES?
Is it also get "out of thin air"?

And would it make sense to have buttons to adjust the timeouts?
