    Replay tool performance patch from Phil · 2fb5c6de
    Shane Snyder authored
    Hack to force replay tool to use one preallocated and initialized
    I/O buffer for all I/O operations. Malloc'ing a new
    (uninitialized) buffer for each I/O operation causes really poor
    performance, likely due to page faults.
