It has to do with our timestamp-based mod detection. On systems with
insufficient granularity, it's easy (via operations done in quick
succession) to get the WC-stored last-known-unmodified timestamp to match
the timestamp of a quite-modified working file, which causes Subversion to
not notice that the file is modified.
