Hi, quite often I find myself using commands like $ ssh foo nc bar 12345 to connect to another host behind a firewall, and I also have a lot of these commands in my ssh config file. Since this relies on the server having netcat available (which a lot don't, or in some really old version that will not shut down properly) it breaks often, and I wonder whether it would make sense to have an

Rafael, Filipe, I am looking at the fixes you apply to sanitizer tests and they worry me. (e.g. https://reviews.llvm.org/D31498) The fixes are mostly mechanical and thus every single change looks safe, but given the amount of changes there is large risk to cripple some of the tests in a way that they will stop detecting failures. When I write a test for new functionality, I always verify that
