 Subject: [Bug general/3014] New: TestRunner hang at  
testTaskForkedObserver, after some ERRORs and FAILs
      To: woodzltc@cn.ibm.com

I am using a script to check out the cvs, build frysk and run the testsuite.
One hour after I started the script, I see it hang at testTaskForkedObserver:

Here is the output:
===================

Running testTaskForkedObserver(frysk.proc.TestTaskForkedObserver)

   at TestRunner.main(TestRunner)

When I look back, I found quite a lot of FAILs, with a similar message:
junit.framework.AssertionFailedError: event loop run explictly stopped
(startChild (Sig_USR1))

These fails start with an ERROR report at testDoCloneAttached:
 java.lang.RuntimeException:
{frysk.proc.LinuxTask@e1f900,pid=8463,tid=8463,state=StartMainTask.wantToAttach}
in state "StartMainTask.wantToAttach" did not handle handleRemoval

Before testDoCloneAttached, there are 51 PASSes.

Additional information:
1. I talked this with Phil on IRC, he confirm similar errors.
2. I am running on FC5.  I ever run the same testsuite against the cvs code I
checked out at 08-05. no errors found, 100% pass for 137 tests in frysk-core
