Remarks
Diff the specified set of dirty files (absolute paths, or relative to the monitor directory), adding transactions to the specified array if necessary. Optionally takes a directory state from which we can retrieve current file system state, without having to ask the FS directly. Optionally exclude files that have changed since the specified threshold, to ensure that related events get grouped together correctly.
