Simple testcase for me is:

No effect on Octane R14000A, as far as lockups. Spikes the CPU usage in 'ps

If I can get my plucky IP32 R10K to boot again soon, I may try it there for
kicks and giggles. Maybe we're also seeing a side effect of the R10K's spec
exec knocking the non-cache-coherent machines out?
Also, tried building the code with the R10K cache barrier on to see if anything
else changes? Generally reserved for kernel stuff, but Peter once speculated
userland might have a use for it.
