Increase the number of ptrace(2)d processes of TestTaskForkedObserver to the max
As Bug 209118 / Prarit Bhargava found that the crashing reason is most probably
race during exiting of ptrace(2)d processes I just found the existing
TestTaskForkedObserver to be the optimal testcase for it.
It can get more harnessed by increasing the number of ptrace(2)d processes
there [attachment] but it is not needed at all.
while :;do ./TestRunner frysk.proc.TestTaskForkedObserver;done

Some trivia 16x repeating of the TestTaskForkedObserver testcase
The requested testcase was already implemented as `TestTaskForkedObserver'.
The testsuite was crashing the kernel before already.
The problem looks fixed for me since kernel-2.6.18-1.3002.el5 as announced in
