if the repo not changed createrepo leave there the .repodate dir

hi,
if i run a
createrepo --update ...
on repo which not change since the last run it create a .repodate temp
dir but leave it there. imho it should have to clean it up.

ps. we test it on centos-5.3's createrepo-0.4.11-3.el5.
pss. i can't create ticket for http://createrepo.baseurl.org/newticket
even if i register:-(
