iostreams are often slightly slower than the C versions, but both are
faster than the disk, so that's not really a problem. The abstraction
gain is usually worth it.
And I'm using memory-mapped files anyways, which goes the complete
opposite way on the overhead/abstraction scale. Reading GiB of data
from disk just takes a long time, no matter what you do.
