I've just checked this, but it does not behave like unix. If you specify 
FILE_SHARE_DELETE you DeleteFile returns success when the file when it's 
in use (but the file it's still there in the explorer) and opening the 
file after deletion fails. However, if you try to create another file 
with the same name this also fails. So you can't just call "remove" and 
recreate the file with the same name. That's a pity.
