In the mean time, I'll be launching some design work on or-dev to make it easier for Tor to switch to a better hash algorithm, once we've got one, or in case we need to jump off SHA-1 in a hurry." https://blog.torproject.org/blog/md5-certificat... Wikipedia says the new SHA3 standard will be announced in 2012. Also, SHA-384 is just a truncated version of SHA-512 (according to Wikipedia), so we might as well use SHA-512 because it uses the same amount of CPU.
