    ext-array: Speed up with unlocked versions of I/O functions.
    
    In my tests this reduced a 2.0 second run to only 1.5 seconds.
    
    Bug #33260.

    temp-file: Use 64 kB buffer for temporary files.
    
    Generally PSPP uses temporary files because it has a lot of data to
    write to them.  The default glibc buffer is only 4 kB.  In my tests
    using a 64 kB reduced runtime from 2.5 seconds to 2.0 seconds, but
    increasing the buffer to 1 MB had no additional effect, so 64 kB is a
    reasonable choice.
    
    Bug #33260.
