we have a remoting process that write csv files... on a quotatized storage
space...
We run out of quota... and we have seen "Sharing violation on path" exception


Reproducible: Always

Steps to Reproduce:
1. create a mini test filesystem (dd if=/dev/zero of=/tmp/test/fs bs=1
count=1M)
2. mkfs /tmp/tesfs
3. mount /tmp/testfs /mnt/test -o loop
4. create a "big" file ...
dd if=/dev/zero of=/mnt/test/test/bigfile bs=1 count=999k

5. run this program 

        public static void Main (string[] argv)
        {
            try {
                using (TextWriter streamWriter = new StreamWriter
("/mnt/test/test/test.txt", true)) {
                    streamWriter.WriteLine
("Coucdfgdfgdfgdfgdgfgdgdfgdfgdfgdou");
                }
            } catch (Exception ex) {
                Console.WriteLine (ex);
            }


            using (TextWriter streamWriter = new StreamWriter
("/mnt/test/test/test.txt", true)) {
                streamWriter.WriteLine ("Coucou");
            }

        }
