I don't think I'd want the actual apt-get command line to be
second-guessing me, so how about this for a feature suggestion (to
update-manager and to synaptic):

If a package takes more than 60 seconds to install, force the "details"
window to open, and also present a dialogue box saying:

$PACKAGE has taken more than a minute to install.  This is normal for
some packages, but might be a sign of a problem.

The following packages depend on $PACKAGE: $DEPENDENCIES

[ Stop installing ] [ Skip this package ] [ Keep waiting ]

Clicking "stop installing", obviously, stops the installation.  The
package that failed is then highlighted in the main window.

"Skip this package" kills the PID of the shell script that apt is
running.  I'd have to check, but I think that apt does the right thing
in that situation.

Clicking "keep waiting" sends the dialogue box away for 5 minutes (then
for 10 minutes, then for 15 minutes...)
