Most are simple refactoring, cleanups and improvements, but still involving two slightly notable changes: + In `filemanager`, now we read the file content based on requested `RelativePos` by `seek` and `read_exact` (rather than `read_to_end` then do slicing). This strategy might be again adjusted in future performance tuning but certainly better than nothing. + Also, I cached more file meta-info in both sides and left a block of comment on `filemanager`'s file reading mentioning the snapshot-state problem (not solved now though). r? @Manishearth <!-- Please describe your changes on the following line: --> --- <!-- Thank you for contributing to Servo!
