The test execution is killable, yet the threadexec process is not.  In fact,
according to top it continuously consumes 100% CPU, requiring a reboot to clear
up the situation.

[Bug general/4052] frysk2130/strace-clone-exec test causes kernel BUG report and process hang

[kris dot van dot hees at oracle dot com]

This problem is still occuring on FC6 with the 2.6.19-1.2911.6.5.fc6 kernel.  It
has been confirmed to reoccur on x86.  So far, x86_64 has not shown this problem
again.

Confirmed to occur on x86 and x86_64 FC6 with 2.6.19-1.2911.6.5.fc6 kernel.

I am adding code tyo the test script to skip running the test on FC6 kernels
known to cause a problem, because it is causes system hangs, often requiring
power cycling the machine.

Is this still an issue? 26 releases later, maybe they fixed that already?
