Thanks Steven,

Just a note: In Boost to 1.39 windows will get the same behaviour as 
unix (you can remove in-use shared memory or named objects), so I hope 
portability will be increased. This in-use removal has been implemented 
using native NT system calls, so that the in-use file is renamed and 
marked as deleted when the last handle is closed. Attached processes 
will continue working in the resource until the last handle is closed, 
just like in UNIX.

Best,

Ion
