This was probably not the operating system but X. If you have a network or
serial connection to another machine or a dumb terminal it should still be
possible to get out of this without hitting the reset button or the power
switch. If you can, get a telnet session to your frozen machine and
kill the X server. That should release the session on the frozen machine
so that you don't get the problems caused by rebooting without a shutdown.
If you have only the one machine, you are stuck, because X won't let you switch
to a virtual terminal to do this.
If you do have to hit the reset button, try to wait for a minute after any
disk activity. That should give the system a chance to sync the disks and
reduce the chance of damaging files; it's not guaranteed though.

You really have no choice but to say yes here. You can't unmount your root
file system without shutting down altogether!
