Since when the process crashes everything within it goes away it's 
inherent to asynchronous sinks to have potential to loose some of the 
most recent logs. I don't see anything that could be done about it.

The only way I can imagine to ensure that logs are guaranteed not to get 
lost  is to use synchronous sink with some fast custom backend. Your 
backend could, for instance, forward logs via shared memory to some 
other process that actually does the writing to whichever persistent 
storage you choose to write to.

But as far as I know there are no such off-the-shelf backends offered in 
Boost.Log.
