Summary:
I have many UIAutomation javascript tests for my iPad app.  After upgrading to Xcode 4.3 on Lion 10.7.3, I see a dialog with the following dialog the first time I run my tests in the Instruments GUI after restarting my box:

Developer Tools Access is trying to take control of another process. Type your password to allow this.

Even if I enter my correct credentials, the test often fails with the following error:

Fail: Could not start script, target application is not frontmost.

When I run my instruments test from the command line, I get the same dialog, and often the same result.  

I also have a script that runs many instruments tests successively.  When I run instruments from this script, I get the following prompt in my terminal:

instruments: Instruments wants permission to analyze other processes. Type your password to allow this.
Name ([my-username]): 
Password: 

Failed to authorize rights (0x20) with status: -60007.
2012-02-28 10:04:19.607 instruments[60398:1203] Failed to connect to local pid watcher service: (os/kern) failure
2012-02-28 16:04:20 +0000 Fail: An error occurred while trying to run the script.
2012-02-28 16:04:20 +0000 Fail: The target application appears to have died

I always get the above output, even when I correctly enter my password.

Occasionally, instruments successfully runs my test, but I can't reproduce that reliably.  Much more often, I get one of the above dialogs or prompts, and then my tests fail.

My user is a member of the developer group, and has administrator privileges.

Steps to Reproduce:
From UI:
Restart system
Profile iPad Application
Choose UIAutomation Instrument
(Authorization Dialog Sometimes appears here)
Add a test script
(Authorization Dialog Sometimes appears here)

From command line:
Run the following command
instruments -t /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/Instruments/PlugIns/AutomationInstrument.bundle/Contents/Resources/Automation.tracetemplate /Users/MyUser/Library/Developer/Xcode/DerivedData/MyiPadProject-btrlvecdbhutdsafmouplbiwlrra/Build/Products/MyiPadTarget-iphonesimulator/MyiPadProject.app -e UIASCRIPT MyTest.js

Expected Results:
No authorization dialog appears, test runs

Actual Results:
Authorization dialog sometimes appears, test fails with:
"Fail: Could not start script, target application is not frontmost."
