             Bug #: 54865
           Summary: [parallel mode] tests timeout on power64
    Classification: Unclassified

On gcc110, a 64 processor ppc64 box, the first one completes in 0.23s when
built single-threaded with -O2, but when built with parallel mode and -O2 it
still doesn't complete after 93m40s cpu time.  Maybe there's something buggy
about libgomp on ppc64, or maybe the libstdc++ parallel mode just doesn't scale
to lots of processors.
