I'm not surprised by the heavy load but a little more notice would
have been nice. This has broken our CI builds for KLEE [1]. We (the
KLEE developers) can fix this by moving our CI to run in an Ubuntu
14.04 environment where the LLVM version we currently require is part
of the official Ubuntu repositories. So I guess this is the impetus we
need to make the switch :)

I (and suspect several others) really on the packages in the APT repo
for our CI builds. You can see see that the LLVM APT repo
is in TravisCI's source white list [2] so there are probably others using it.
