Alexander Motin 01c0f8bef3 MFV r337190: 9486 reduce memory used by device removal on fragmented pools
In the most fragmented real-world cases, this reduces memory used by the
mapping from ~1GB to ~50MB of RAM per 1TB of storage removed. Less
fragmented cases will typically also see around 50-100MB of RAM per 1TB
of storage.
