+Summary: BufferedStream does not use internal buffer\cache in some conditions...
+Description of Problem:
+In BufferedStream on Position property set internal buffer will reset in 
+any case, even when new position of stream still in limits of our internal 
+Steps to reproduce the problem:
+1. Open stream|data throw BufferedStream class
+2. store stream position
+3. read 20 bytes
+4. restore position of stream
+5. try again to read 20 bytes
+Actual Results:
+on next (5) read operation bufferedStream will call wrapped stream, but it 
+still has needed data in internal buffer/cache
+Expected Results:
+simply update internal variables which indicate stream position, without 
+re-read and additional calls to wrapped stream.
