This PR fixes - close leaking bandwidth report channel leakage - remove the closer requirement for bandwidth monitor instead if Read() fails remember the error and return error for all subsequent reads. - use locking for usage-cache.bin updates, with inline data we cannot afford to have concurrent writes to usage-cache.bin corrupting xl.meta
