make revlog.addgroup pass its file handles to addrevision This should fix issue255. It looks like the problem there happens when addgroup calls addrevision to add a full revision, and addrevision decides to split the index file into a .i/.d pair. Since addgroup has an open file handle for the index file, the renaming of the new .i file to its final name fails on windows.
