[Bug general/5902] New: 2.6.24.3-12.fc8 kernel breaks frysk test suite

[mark at klomp dot org]

With 2.6.24.3-12.fc8 on x86 a make check almost always fails (x86_64 seems fine
though). Downgrading to 2.6.23.15-137.fc8 makes make check (at least in
frysk-core) completely clean again. The tests fail (and the TestRunner gets
killed!) somewhat randomly. It is easily reproducible through something like:
./TestRunner -r 100 frysk.proc.TestTaskTerminateObserver
Which always fails within a couple of rounds with as output:
  frysk.sys.Errno$Einval: tkill: Invalid argument (task 0)

On x86-64; look the same?

Running testGetTasks(frysk.proc.TestProcGet) ...ERROR
  frysk.sys.Errno$Einval: tkill: Invalid argument (task 0, signal SIGCONT (18))

This likely means that readdir of /proc/PID/task is finding a dirent entry of "0".
