It'd be nice to have a test which actually sends a non-zero signal. Setting up (and killing) an entire process group might be a bit of an overkill, but we can at least do a trivial process group of one. You can basically take the existing EXPECT_DEATH test in kill_test.cpp, and just add a setpgrp(0,0) call to actually put the child in a separate process group.
