Hi Kazu,

In the alioth shootout, on a quad-core Intel Q6600, 64-bit GHC does
about 5.3M context switches per second for the thread-ring benchmark;
that's 186 nanoseconds per context switch. I think the amount of
overhead will be reasonable here.

I'd be quite interested to see whether stm beats MVars here or not.
