    Hi,
    
    I open a file with "append" mode, when i cr_checkpoint and cr_restart
    the process, the output of the program really appends to the output file.
    but i think it should write to the position which it was checkpointed.
    
    my test program is the file_counting.c with modifying:
     fp = fopen(filename, "w");
    to:
     fp = fopen(filename, "a");
    
    when i cr_restart the context file, output file looks like:
    
    ***************************
    ...
    Count = 15
    Count = 16
    Count = 17---------cr_checkpoint
    Count = 18
    Count = 19
    Count = 17 --------cr_restart
    Count = 18
    Count = 19
    ....
    ****************************
    
    but i think the right way is not like this.
