Almost twenty years ago, found a debug logging function using O_SYNC. Took it out. Test ran so fast that a teammate said that they thought it didn't run. Now, of course, there's zero reason to write every debug output with O_SYNC. Classical case of cargo-cult programming. I'd like to say I've never seen something like that again, but then I'd be lying.
