 I run this:

 {{{
 managed_mapped_file myMem( open_only, "mfile.bin" );

 void* ptr = myMem.get_address();
 std::size_t size = myMem.get_size(); // ==1024*1024

 int* pInt = (int*)ptr;
 *pInt = 1;

 myMem.flush();
 }}}

 and after that I run it again, but it doesn't work because of


 {{{
 while(value == InitializingSegment || value == UninitializedSegment){
             thread_yield();
             value = atomic_read32(patomic_word);
          }

 }}}
 InitializingSegment is always 1
 It seems that I can't write 1 and it seems to be wrong.
