In >=portage-2.1.2_rc4-r2 t does that now for installed package (see bug #158931). For /var/cache/edb/dep the sqlite module is available (requires pysqlite or python-2.5 with sqlite support enabled). > This is the same problem that git ran into, leading to pack files, > or that cnews and inn hit, leading to the rotating spool files. > > It may work reasonably well on a headless server, with only a few > packages installed.

That's been fixed for bug #158649. If you make extensive use of PORTDIR_OVERLAY then you will probably want to run emerge --regen after each sync to avoid having to generate cache at other times. > I'll also be posting a bug report about unmerging.
