Log Message:
In an ideal world, make_playpen() and leave_playpen() would maintain
a stack of directories, we'll do with a save/restore_dirs cludge for
now. => Fixes the bug I mentioned yesterday that shows when one pkg
installs another (depending) pkg via FTP.

Fixed another bug with extract-in-place when the destination dir is
already there.
