maps.RevMap: disable GC while loading the revmap The revmap load process creates lots of tiny objects. With just the bare minimum Mercurial runtime, loading a million-file revmap goes from 6.83 seconds to 6.28. For longer running processes (e.g. hg push a series of changes) the difference will probably be dramatic.
