First, the default build of Racket 7 (according to the plan Matthew

Second, the "cs" variant of Racket will map Racket futures onto Chez
pthreads, and many more operations are future-safe in that variant.
However, Racket threads still do not run in parallel in the "cs"
variant -- you need to use futures or places to make use of more than
one hardware core from Racket.


Thanks for the clarification.  I'm not on the developer list - I've just read the blog entries.  I have pretty much suspected all along that Racket would not rush to adopt kernel threads (other than internally to implement places).
