Comment #141 on issue 2148 by [email protected]: vertical skylines should use stencil integrals

At any rate, don't be surprised if the regtests pass on decent development machines where contributors test manually or semi-manually (with Patchy) and can intelligently supervise the process (including visually checking the patch before testing it). On Grenouille server, I'm setting things so that in the near future it will test patches and send results completely automatically, which implies setting limits on CPU time, file size and memory usage, building with a user without exposing Git push access and other services... any small mistake in this complex setup may lead to a crash not related with the patch.
