I've tried to look through the sources of Elk, another extensible scheme
interpreter which seems to avoid the embedding problems of main, but
couldn't figure how it's done there. 

Thinking of the the multiple sripting language support of gnumeral reminds
me of Corba, especially Orbit which is currently used with Gnome. Would
using guile set up as a scripting server also exhibit that dilemma? For Ilu,
there were once experimental guile bindings. 

At least gh_enter loads now boot-9 again, which solves tons of problems that
annoyed us before.
