Re: [Libguestfs] [PATCH] Fix cleanup of guest handle when installing with local files

Change 13412f7629133b25fda32c35fdb0276e22de3445 caused Config to keep a reference to the guestfs handle in certain circumstances. This caused a regression in the cleanup code because the handle was no longer closed in close_guest_handle. This change explicitly drops the reference to $config before closing the guest handle. It also localises $guestos, which also keeps a reference to the guestfs handle in an eval block.
