Writes to the cookerdaemon log and/or the lockfile were meaning the parser
cache was always being invalidated and reparsed. This is unnecessary so
spot accesses to these two common cases and ignore the files from a reparse
perspective.
This doesn't remove many sources of reparse but does improve several
common cases.
