Hi,
After this merge, I'm seeing lots of timeouts on arm (using QEMU).
Is this "expected"? (as in: should I increase my timeout value)

I wouldn't say it's expected; this is the first time Cilk+ has beensupported on ARM. It could be a bug in the ARM support in the runtime,an ARM compiler bug or even a bug in the ARM QEMU support.

Probably the first step is to see if it's working properly on realhardware. That would at least allow us to eliminate QEMU from theequation if it's failing in the same manner on a real machine.
