Are you sure that's the case?  time git-name-rev --stdin < /dev/null 
gives the same high startup time without looking up anything.

Anyways, it would be great if someone could try to fix that, since a 
6-second startup time on a repository like linux-2.6 makes the --stdin 
option unusable for applications like gitweb (for which it would 
actually be quite useful to reduce the number of forks).
