Dan Berindei commented on ISPN-10377:
-------------------------------------

I've changed the type from bug to feature request because the {{CacheEntryExpired}} listener is intentionally not invoked while holding the lock (with {{pre == true}}).

> Hi,
> it looks like that CacheEntryExpired callback is called without a key lock held like CacheEntryRemoved. In this scenario I'm unable to synchronize keys if reaper thread is enabled.
> I'm attaching simple test case that will show this issue. Because it's a classical race condition please start this test multiple times if result should be ok.
> Thanks in advance!
