105      + Some liberties are take with preloaded modules using one another's
106        symbols.  This only works (portably) because the modules that do it
107        (m4.so and gnu.so) are both statically linked into the core.  Need to
108        investigate how this can be supported for any module, on platforms that
109        don't support backlinking.  Maybe exporting symbol name/address pairs
110        into a table maintained by libm4, and only using module symbols through
111        that table in other modules.
112    
113      + On a related note, modules should be able to declare that they require
114        other modules to be loaded before they can work -- and the module loader
115        should take care of that.  Should such required modules be fully loaded
116        into the symbol table?  Or merely loaded into memory so that the C level
117        code is callable?
