OK, I've got two ideas to file in the "really seemed like a good idea

at the time, but on further reflection..." bucket with these changes.

1. Checking the media before frobbing the disks was a fine idea, and
   I wish it could have worked, but that leads to a rather difficult
   situation when you need to mount the media someplace and you're about
   to:

	a) Chroot away from your present root.
	b) Newfs the root to be.

   You're basically screwed since there's no place to stick the mount
   point where it will be found following the newfs/chroot (and eliminating
   the chroot in favor of just using the "root bias" feature would work
   great for the distributions but not the pkg_add calls done by the
   package installer).

2. Automatic timeout handling.  I don't know why, but alarm() frequently
   returns no residual even when the alarm didn't go off, which defies
   the man page but hey, since when was that so unusual?  Take out timeouts
   but retain the code which temporarily replaces the SIGINT handler in
   favor of a more media-specific handler.  This way, at least, if it's hanging
   you can at least whap it.  I think the timeout code would have been losing
   over *really slow* links anyway, so it's probably best that it go.

This should fix NFS, tape & CDROM installs again (serves me right for getting
complacent and using just the FTP installs in my testing).
