Why?

Even if the application handles the signal, the point of this debugging is
to have the kernel report the reason for the fault.

Just because the application has installed a SIGSEGV handler to print some
nice "oops" message, and to cleanly shut down (eg, like Xorg) doesn't mean
we should hide this debugging.  In fact, as such handlers generally get in
the way of getting a decent dump from the application, having the kernel
report this information is even more valuable in this situation.
