The same way one would do this for uploading images onto a server,//! we stage pushes such that objects unpack into a separate bare repo//! under the incoming prefix, because we treat a push as real only once//! every object it referenced actually made it over.//!//! Hence aborting is as simple as removal of the directory that//! represents the push in flight.//!//! "Why not use `GIT_QUARANTINE_PATH`?" - because we never forked `receive-pack`.//!//! If you were wondering, this `sweep_incoming` is for a crash between a stage//! and migration that would otherwise leak a staging dir.
