the system does offer explicit support to do this. If you create
two files with sys->file2chan. Open one side and then make a clean
namespace, mount the fd. Open the other side and call sys->export.
Now all you need is limbo program thats alt's the four io channels
copying mount.read -> exportfs.write and mount.write->exportfs.read.
What you see in the bodies of the messages are STYX which can
be interpreted however you like.
