[Bug general/3633] New: fstack hangs

[cmoller at redhat dot com]

After running 

    ./TestRunner -r 10 frysk.proc.TestProcStopped 

in one xterm until it hangs, 

    fstack `pgrep funit-child` 

run from a second xterm also hangs, and stays hung even after TestRunner times
out.  Ctrl-C kills it.
