    thread_timeout: document additional caveats
    
    Again, for the one thousandth time, timing out threads is very
    tricky business :<

    As usual, test with the latest released version to avoid
    surprises.

    coolio+xepoll_thread*: use shutdown() for keepalive timeout
    
    Triggering Errno::EBADF is tricky in multithreaded situations
    due to possible race conditions and yet-to-be discovered bugs.
    shutdown(2) is also safe against apps the fork() internally but
    do not execve(2) nor set FD_CLOEXEC.
    
    n.b. calling fork() after pthreads are spawned may not be safe
    on all platforms w.r.t. malloc, but /is/ the case for glibc on
    GNU/Linux.

    epoll*: favor shutdown(2) for keepalive timeout

    fiber_pool: take Fibers from larger pools faster
    
    Array#pop can be significantly faster than Array#shift on large
    arrays (especially since we push into the Array).  This is
    because Array#shift needs to shift all elements in the array,
    and Array#pop only needs to shorten the array by one element.
    The Fiber stack may also be hotter in CPU caches when we choose
    the most-frequently used stack.

    we last updated.

    test_isolate: bump unicorn and kgio versions for testing

    working.

    stream_response_epoll: fix for unicorn 4.3.x
    
    unicorn 4.3.x now calls shutdown() explicitly on the socket,
    so we can't just rely on a dup()-ed FD to keep a socket around.

    tests: require sleepy_penguin 3.1.0 or later
    
    We'll be making the XEpollThreadPool users depend on this, too.

    Starting with "$((" can be ambiguous and confused for shell arithmetic.

    http_server: fix log message if using Base (no concurrency)
    
    Telling the user worker_connections=50 when using the Base
    concurrency model is misleading.
