Yes, from http://www.cygwin.com/ml/cygwin/2005-02/msg00706.html

"... There's no magic, there's no getting around the basic paradigm 
of windows filesystems that require that all outstanding handles 
of a file be closed before it can be deleted." 

and relating to overwriting in use files 

"... For one thing, the file replacement issue is nowhere near
as simplistic as you make it out.  "In use replacement" under windows
amounts to placing an entry in the registry telling the system to move
file A to file B upon next restart, and then put a copy of the updated
in-use file at location A and prompt for a reboot."
