|Title||Can't implement incremental condemn|
|Assigned user||Gareth Rees|
|Description||The MPS currently suspends the mutator during whitening. This is because the pool whiten methods read the buffer data in order to determine what to condemn in a buffered segment, and it is not safe to run this concurrently with the mutator. See request.dylan.160098 .|
|Analysis||The solution needs to be on a pool-by-pool basis. Ideally:|
1. the pool should not examine the buffer during the whiten step;
2. during fix the pool should ignore fixes to the unallocated portion of the buffer;
3. during reclaim we mustn't free a buffered segment, even if it appears to contain no live objects.
