  o Minor features (performance):
    - Avoid parsing the same protocol-versions string over and over
      in summarize_protover_flags(). This should save us a huge number
      of malloc calls on startup, and may reduce memory fragmentation with
      some allocators. Closes ticket 27225.
Memoize summarize_protover_flags() Our tests showed that this function is responsible for a huge number of our malloc/free() calls. It's a prime candidate for being memoized. Closes ticket 27225. 2018-10-19 21:04:45 +02:00			`o Minor features (performance):`
