No one calls C#, JavaScript and Python memory unsafe because their runtimes are implemented in C. Nor do I expect CF to not use Linux or Nginx because they are written in C. We have to live with C but I expect everyone who does anything safety or security critical to do everything they can to minimize the amount code that is susceptible to this class of bug.

Using a runtime with a safe language on top is a perfectly good example of doing that.

Logic errors causing leaks will always be a threat, but we shouldn't be leaking because of pointer arithmetic problems in custom C code. Not 2017.
