I have no idea! AFAICS, tee and cat (which work properly) use write() for
outputting, but this function has the same problem when I call
it. -mno-cygwin makes that problem go away.

Did you do this on purpose or something? It seems a bit weird that a write
takes _excactly_ 1/100th of a second, both on my GeForce-powered desktop
comp. and my weak laptop...
