45 Parameterize StatusCollector to produce copy only when needed. And HgDataFile.metadata perhaps should be moved to cacheable place?

63 ReadOperation gets buffer (of whatever size, as decided by FS impl), parses it and then reports if needs more data. 66 ReadOperation gets buffer (of whatever size, as decided by FS impl), parses it and then reports if needs more data.
64 This helps to ensure streams are closed after reading, allows caching (if the same file (or LRU) is read few times in sequence) 67 This helps to ensure streams are closed after reading, allows caching (if the same file (or LRU) is read few times in sequence)
