But I'm not sure you can call that an implementation bug. The flaw is to consider that 2 files with same name and same timestamp have the same content, or moreover that the content of a single file has not changed, if the timestamp has not changed A lot of batch, or cvs import, commit or extractions, can generate a lot of files with same name and same timestamp.
