Hello Oleg, The first example which comes to mind - because I recently implemented this - is HTTP uploads: the input stream can hold N files (the value of N not known ahead of time), and each upload can go to a separate temporary file. If the request stream fails early (e.g. client browser closes connection), any already-created temp files and any open file handles must be cleaned up.
