This means that any Git program that is in the process of creating new objects, that has not yet hooked them up, has a grace period. pid lock, meaning that on a busy repository we may run many of them concurrently. bigPackThreshold If non-zero, all packs larger than this limit are kept when git gc is run. Eventually these reflog entries are old and stale and unlikely to be useful any more, and git reflog expire will discard them.

If it finds housekeeping is not needed it exits without doing any work. It can also omit any unreachable objects from the pack, turning them instead into loose objects. git fetch --prune is the best utility for cleaning outdated branches. The mode is 100644 or 100755 for a blob object, 004000 for a sub-tree, 120000 for a symbolic link, and so on. See for additional details.
