Interesting.  Would it make sense to add a paragraph to the "Projects
using Kawa" web-page?

But is that other file required by the file that uses it?
Doing so is optional, but a good idea.   If you require all the
needed modules, Kawa can generate better code.  Also, you can
compile with
 (module-compile-options warn-undefined-variable: #t
			  warn-invoke-unknown-method: #t)
which is very useful for catching mistakes.

However, requiring the module that exports make-canonic-name is
optional.  If you don't, it should look for make-canonic-name in
the dynamic environment opf the current thread.

When a module is loaded, it's definitions are no longer automaticlly
placed in the global (or thread's) environment.  However, I think
the loadClassFile shoudl take care of tha, since it calls defineAll.

Quite likely, since they way thread-specific environments and Location
sharing was done was changed.  However, I don't know specifically what
caused your system to fail.
