# These are very ugly.  They are needed to suppress errors inside (eg)
# NPTL's pthread_cond_signal.  Why only one stack frame -- at least we
# should see the wrapper calling the real functions, right?
# Unfortunately, no: the real functions are handwritten assembly (in
# the glibc-2.5 sources) and does not create a proper stack frame.
# Therefore it's only one level of unwinding before we're back out in
# user code rather than the 2 levels you'd expect.
