The way the DNS is written it is serial lookups, and to reverse the lookups you would need to rewrite the whole lookup and result merging sequence. We talk occasionally about making the DNS lookus asyn and using the first response immediately, but nobody has yet had time to write that code. Patches welcome.
You should be able to reduce dns_timeout to a few seconds safely. The iteration is not through all remote DNS servers, but throughthe set of your own internal ones. A small set is recommended when facing this problem.
