update on S3 memory leaks

The remaining leaks are in hS3. The leak with encryption was worked around
by the use of the temp file. (And was probably originally caused by
gpgCipherHandle sparking a thread which kept a reference to the start
of the byte string.)

 S3 has memory leaks
 
-## with encryption
+Sending a file to S3 causes a slow memory increase toward the file size.
 
-One only occurs with encryption. It was was fixed for bup, but
