With my repo that contains a bunch of 50MB tarfiles, I've found I must
specify --window-memory as well to keep repack from using nearly unbounded
amounts of memory.  Perhaps it is the larger files found in gcc that
provokes this.

A window size of 1000 can take a lot of memory if the objects are large.
