hello, everyone:

    I¡¯m a newbie to boost::interprocess, It¡¯s really a cool library, 
so I try to write a simple program to test mapped file, it¡¯s really
simple:

#include <boost/interprocess/managed_mapped_file.hpp>
using namespace boost::interprocess;

int main()
{
    managed_mapped_file mfile(open_or_create,
                                 "/home/fractal/log.bin", 
                                1024);    //hanging here.
    return 0;
}

but it¡¯s hanging on the creation of mapped file, I test it both on 
ubuntu 11.05(in virtualbox) and openSuse, the same problem remain. 
I¡¯m sure the file exists, and I traced down the source code, it seems 
the program stuck in a while loop in function priv_open_or_create(...).

except that, if I set the third argument of constructor from 1024 to 1,
it¡¯s even throw a exception( not good).

any seggestion is appreciated!!!
