That's clearly undesirable, tho I do know that it happens in
various cases.  In many cases it can be fixed pretty easily, tho.

So if you provide a testcase, or at least explain what it is you were
doing with that URL, maybe we can actually fix the problem.

PS: One common situation where C-g is unresponsive is when the redisplay
is too slow (e.g. navigating in a vvveeerrrryyy long line).  In such
a case, iconifying the frame displaying the "offending" buffer may get
you back in business (provided you have another frame or the
emacs-server open).
