 this PR can be closed. the results described by jan when running the example
 code can no longer be reproduced (running 9-CURRENT). both printfs return a
 unique address.
 
 the problem described by rwatson however still exists (again running
 9-CURRENT). if mmap is called with MAP_FIXED|MAP_ANON a segfault will occur.
 this problem however seems completely unrelated to this PR.
