This is a bug in the futures-enabled? implementation (it is erroneously returning #f regardless of whether futures are in fact enabled). If you used the installer futures should be enabled on your platform (futures-enabled? doesn't have any effect on whether futures run in parallel or not). I'm pushing a fix for this. > > > Regards, > > Rodolfo Carvalho > -------------- next part -------------- > An HTML attachment was scrubbed... > URL: < > http://lists.racket-lang.org/users/archive/attachments/20120807/df2ec11b/attachment-0001.html > > > >
