Well, this is taken right from the implementation of scm_module_lookup()
right?  I applied it locally. Did the guile servers failed while looking
up symbolically referenced procedures ("No such procedure: xxx")?

Hm.  I waited to appliy these changes until the guile developers finished
their gc rewrite and found a API which does not change to often anymore...
Do you know about the state of development?

Basically we must differentiate 2 cases where the scm_must_*() functions
are used in Serveez:

 1. free'ing pointers returned by e.g. gh_scm2newstr() -> the macro
    scm_c_free()
 2. allocating/freeing the smob data structures and pointers inside these
    structures

Is there a document telling what we need to use (the correct way) in the
new guile? I've seen loads of these malloc()/free() functions... quite
confusing for a non-guile developer (at least at the first glimpse).

Thanks in advance,
