checkpoint: Mostly working This seems to work except for I/O timing. Reads are sync and writes are async, so this sequence fails: - Object x flushes - Object x is reused as y - Another object is taken as x - New object x reads -> Stale data is read Two potential solutions from here: 1. Implement async reads. 2. Hold ref to object until write completes. (1) is complicated, but more correct. Writes may stay in buffers for quite some time (typically 5 seconds), during which time the dm-compress object cannot be released. 2019-10-22 04:39:27 +02:00			`dm-compress-y += \`
