Thank you.

But neither openfiles or fuser seem to work in this case, even if I
have a file open in my bash shell, and call fuser in the same bash
script:

bash -c 'command exec {n}</mynfsmount/myfile.txt ; echo "fd=$n" ;
fuser -a /mynfsmount ; true'

gives

fd=10
/mynfsmount:

(no processes listed, which might be correct, as maybe a non cygwin
process has that file open)
