cleanup of revlog.group when repository is local revlog.group cached every chunk from the revlog, the behaviour was needed to minimize the roundtrip with old-http. We now cache the revlog data ~4MB at a time. The memory used server side when pulling goes down to 35Mo maximum whereas without the patch more than 160Mo was used when cloning the linux kernel repository. The time used by cloning is higher mainly because of the check in revlog.revision. before 110.25user 20.90system 2:52.00elapsed 76%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+708707minor)pagefaults 0swaps after 117.56user 18.86system 2:50.43elapsed 80%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+748366minor)pagefaults 0swaps
