I tried, but it's taking *too* long. I was able to reproduce the
problem on x86_64 at length of 0x40000000 and based on some rough
extrapolation, it would take about 4600 hours to complete.
Maybe I could cap the run time for a minute and kill the test. Does
that sound good enough?
Thanks for making me do this though, since I actually found a bug in
my fix while trying to figure out how long the test could run. I'll
post an updated patch.
