Summary: Loosefiles are quite slow to repack, and this is significantly affecting laptops as the repack can potentially run for hours when a large amount of loosefiles are present. One of the reason for that is that an incremental repack really isn't incremental for loosefiles as all of them are repacked at the same time. Instead let's repack only one of the top-level directory at a time. Reviewed By: quark-zju Differential Revision: D14690348 fbshipit-source-id: ffba49840302ae0d99e32db410647e83e213fe64
