TBH the Boo Console doesn't matter since it has to load the assemblies
to run them. It's out-of-process so can be restarted (in theory).

A couple of notes:

The loading of referenced assemblies into the MD process prevents
rebuilding Boo projects correctly:
We have had segfaults reported on Debian due to the assembly loading:

There is a patch in SVN for updating the boo console to use
GtkSourceView2: https://bugzilla.novell.com/show_bug.cgi?id=470460

It might also be nice to be able to build the Boo Binding without the
Boo Console, since this would simplify the dependencies, enable us to
e.g. ship it on OS X

Alternatively, porting the "Console" code to Mono.TextEditor and
moving it into core would make it near-trivial to add other consoles
such as Miguel's C# REPL.

And while we're on Boo Binding issues, IIRC  recent Stetic changes
would make it much easier to add GUI builder support
