You are right. It is useless writing.
How about adding new abandon flag to db->close()?
If the flag is specified, writing process is omited.
We can set this flag to 1 for all db files which was opened
with DBOP_REMOVE flag.

[libutil/dbop.c]
void
dbop_close(dbop)
{
        int abandon = dbop->openflags & DBOP_REMOVE ? 1 : 0;
        ...
        (void)db->close(db, abandon);

[libdb/bt_close.c]
int
__bt_close(dbp, abandon)
        DB *dbp;
        int abandon;
{
        /* Sync the tree. */
        if (!abandon)
                if (__bt_sync(dbp, 0) == RET_ERROR)
                        return (RET_ERROR);
