  "message": "Use thread-local storage for PRNG states if fork-unsafe buffering is enabled.\n\nWe switched from thread-local storage to a mutex-pool in 82639e6f53\nbecause, for highly-threaded processes, the memory used by all the\nstates could be quite large. I had judged that a mutex-pool should be\nfine, but had underestimated the PRNG requirements of some of our jobs.\n\nThis change makes rand.c support using either thread-locals or a\nmutex-pool. Thread-locals are used if fork-unsafe buffering is enabled.\nWhile not strictly related to fork-safety, we already have the\nfork-unsafe control, and it\u0027s already set by jobs that care a lot about\nPRNG performance, so fits quite nicely here.\n\nChange-Id: Iaf1e0171c70d4c8dbe1e42283ea13df5b613cb2d\nReviewed-on: https://boringssl-review.googlesource.com/c/31564\nCommit-Queue: Adam Langley \u003cagl@google.com\u003e\nReviewed-by: David Benjamin \u003cdavidben@google.com\u003e\n",
