Perhaps. The daemon side of the credential-cache helper does not work quite like ssh-agent, though, in that it tries to be ephemeral. So after starting, you have 30 seconds to give it some data to cache before it will exit. Normally this is fine since it's started by the client side of the helper, which will then immediately supply it with data. So after starting it, you'd need to immediately prime it with data, either manually or by running a Git command. And then hope that command, including time to talk to the other side on the network and for you to type your password, does not exceed the timeout. -Peff
