Temporary (Ivy) file created by System session will not be deleted

In the documentation of Ivy File (emphasis mine)

A File object can be used to read/write temporary or persistent data. IvyScript Files are created in a confined area that belongs to the running application. Temporary files are created in a session-specific file area and are automatically deleted if a session ends. Temporary Files can be made persistent.

If a temporary File is created, it will be located at {app}/files/sessions/{sessionId}/. The files then will be deleted if the session is invalidated.

Unfortunately, this isn't true for temporary files created by SYSTEM user. The SYSTEM user's session is always have the id of 0, hence all files created in SYSTEM user's session will be located at {app}/files/sessions/0/.

It seems that Ivy Server will never invalidate SYSTEM user's session, thus all files located in the directory will by left there undeleted (same as persistent file).

I don't know whether this is a known fact as a consequence of the implementation that SYSTEM user will never be invalidated or it should be considered (somehow) as a bug?

Thanks for considering my question.
