Add Cyclone support
I have made a feature request to the Cyclone developers to add built-in support for behaviour that is necessary to make Geiser work well.
Cyclone is a new R7RS Scheme that uses Chicken-style Cheney-on-the-MTA for garbage collection, but which supports native threads via an SRFI-18 interface. It performs about as well as Chicken in single-threaded tests.
