Bug Description

Since the output file is simply overwritten when dumping the LRU list, we may end up with a partially written dump file in case of a crash, or when making a backup copy of it.

The more safe approach would be to dump to a temporary file first, and then rename it to the actual dump file.

What's the status of this bug? Is it in progress? Can we expect it for next 5.1 and 5.5 releases?

It is fixed by the linked MP. What needs to be done to get it merged is to make LRU dump ordering optional. It stalled as a low-priority task, but can be completed for the next 5.1 and 5.5 releases. I'm going to create a blueprint for the MP.
