James Manning <jmm at users.sf.net> wrote tiobench.pl and also provided several fixes and improvements to other parts of the tiobench project as a whole. He also has relentlessly fixed typos and Mika's misspellings everywhere. Jakob Østergaard <jakob at ostenfeld.dk> proposed fsync fix, and option for sequential writing to prevent file fragmentation. Sami Korhonen <sjkorhon at cc.hut.fi> noticed thread_attr not initialized bug. Numerous other contributions from fearless benchmarkers.
