[Mono-dev] 2.6 preview 1

[LKeene]

Hey Alan,

I understand. I've been through the algorithm and it's very sound. It
screams on Microsoft .net, runs nicely (but a little slower) on Mono runtime
and Linux. Bogs down like crazy on Mono + Mac. I have a sneaky suspicion
it's the way the calling thread is waiting for the worker threads to finish
(WaitHandle.WaitAll(...)). Maybe Mono's Mac implementation of this is very
inefficient?

-L

I'm going to prepare a compact test case that illustrates the behavior.
