           Summary: NRWT doesn't print exceptions
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: wangxianzhu at chromium.org
                CC: tony at chromium.org, dpranke at chromium.org


On exception occurred in the main program, NRWT just exits with status EXCEPTIONAL_EXIT_STATUS but doesn't print the exception, making it difficult to debug the issue.

To test:
1. Create a syntax error in port/webkit.py
2. Run NRWT

Actual result:
NRWT just exists without any error message

Expected result:
NRWT should print the error.

In addition, if some worker raises some exception, NRWT just print the stack trace without the type and message of the exception.
