VNC authentication time-out?

[Mark G. Spencer]

I've just done some testing with UltraVNC and noticed that it doesn't
appear to have a VNC authentication time-out - or at least not less
than 5 minutes.  ;)

I'm wondering if RealVNC has a (default) time-out?  And if anyone has
any insight into this particular function?  I would think it would be
a good idea not to leave the port open waiting for authentication for
an unlimited period of time - if only to make reading logs easier.

Thanks for the info!
