   main() fails because shared libraries are allocated just below the initial

   the area occupied by the shared libraries.  Sun knows about this bug
   but has no obvious fix for it.  */

   the mappings in it's address space.  See the comments in map_to_address()
   for details.  This is expected to only be a short term solution.  Yes it
   is a kludge.
