http://github.com/juranki/couchdb/commit/e17bc9f988b2ad2e59ce1f654e0433cabd=
63e677 worked for me in light manual testing.

Compaction test in the test suite did compact the database but reported fai=
lure because of this error:=20

> During compacting, rename the current DB file to a .old file is not allow=
ed on Windows.
> A possible workaround for this could be:=20
> 1. Close current DB file (.couch);
> 2. Send db_updated to update to use .compact;
> 3. After 5sec, delete the .couch file;  ---- This is done in a linked pro=
cess, after that, this process send a message to update_loop;
> 4. After received the message in update_loop, close current DB file which=
 is a .compact file, then rename it to .couch;
> 5. Finally, db_updated again to use this new .couch file.
> Maybe, there would be a "pause" in service?
