    Things like these make me glad I’m on FreeBSD with dtrace. While not perfect, it’s much better than this. I know work is being done to add dtrace-like tracing to Linux but it’s quite immature and, in the little I’ve looked at it, not as pleasant and cohesive. I’m not the type of person that uses dtrace every day, but when I do need it it is a life-saver. Oh, how the world would have been different if Google chose FreeBSD (or Solaris was open sourced in time for then to use it).
