Is there a way to remove the authorization prompt from command-line instances of Instruments (Xcode)?

I am currently using Instruments via a bash script to initiate the command-line interface to start up runs of the Automation plug-in.

With 4.2, this worked well enough, however with the upgrade to Xcode 4.3, I am now being prompted for an authorized user to 'analyze other processes'. No user is ever actually authenticated, even if the correct credentials are granted. I get the following error:

Failed to authorize rights (0x20) with status: -60007.
2012-02-27 19:30:37.232 instruments[54151:1c03] Failed to connect to local pid watcher     service: (os/kern) failure

Even with the authentication failure, the Automation plug-in executes, however this requires my script to have a physical babysitter enter credentials, which in many ways defeats the purpose of these command-line runs. Is it possible to add the user details as arguments? Or is there some other way to skip over this prompt without requiring a person at the keys?

This authorization dialog appears when you try to run UIAutomation tests from the GUI for the first time.

Once the authorization dialog has been answered in the GUI, the prompts stop appearing on the command-line. This kind of work-around doesn't seem valid as an 'answer' though.

Here's a wonderful command that may work for you:

security unlock-keychain -p [password] "${HOME}/Library/Keychains/login.keychain"

It's the command-line way to gain access to a keychain on the Mac. I haven't tested it with Automation, but it's how I've integrated my iOS builds with Jenkins.

(Replace [password] with the password)
