Yes: The `ffi/unsafe/vm` library provides access to Chez Scheme's `eval`, so you can use `(vm-eval '(fork-thread ...))`. Even more directly, you can use the `ffi/unsafe/os-thread` library to create a Chez Scheme thread. No: Accessing Chez Scheme directly is unsafe, because you can break Racket invariants, and there are some limitations on using Chez Scheme functions in Racket and vice versa.

[racket-users] Using Chez Scheme libraries with Racket CS?
I'm new to Racket and have not yet played with Racket CS. My question is whether the Chez Scheme libraries are available. For example, is it possible to do something like (require chezscheme) and then use (fork-thread ...) to create a native thread? -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
