Hi,
some time ago I had exactly the same process going on on my box and asked
the question here on the list. This is what I have been told:

Subject: Re: Changes made to /etc/ioctl.save follow
Message-ID: <bqkidu$ita$1@news.cistron.nl>

It's init (process #1). /etc/ioctl.save saves the stty(1) settings
of the console.
This is because originally, Linux and Unix didn't have a way to
specify the console speed, parity etc at bootup which for a serial
console is important. So if you boot single-user mode, at the moment
you leave single-user mode the settings of the console are saved
in /etc/ioctl.conf. The next time you boot and init is started,
it restores the console settings from /etc/ioctl.save
Now today you can set the console speed, bits and parity on the
kernel command line when booting, so it's not all that important
anymore. So in sysvinit-2.85 the ioctl.save code was removed.
Current testing/unstable doesn't have a /etc/ioctl.save anymore.
