Note that the 1 in 1 million figure is for 100 million IDs generated, that is, after 100 million generated IDs there's 1 in a million chance that two of them are identical.

I've watched as the application we develop at work has switched from ancient single and dual core Linux boxes to (now) dual-dodeca-core boxes and all sort of "completely impossible" races have surfaced. All progressively more "impossible" as the number of cores and their speed has kept on increasing.
