I notice that the thread-safe initialization of guile by
scm_with_guile() seems to have been fixed in guile-2.0.10, but the
loading of modules remains not thread-safe.

Has thread-safe module loading turned out to be too difficult to do, or
is it still something that is likely to happen in the future?
