-"""Removes ViewHostMsg_Close and alike from testcases. These messages are an
-annoyance for corpus distillation. They cause the browser to exit, so no
-further messages are processed. On the other hand, ViewHostMsg_Close is useful
-for fuzzing - many found bugs are related to a renderer disappearing. So the
-fuzzer should be crafting random ViewHostMsg_Close messages.
