Yes.  A lot of people have this impression that libc and stdio are
these slow, inefficient hulks that must be avoided for performance.
But in many cases, you have to spend a fair amount of time to do
better than your vendor.  And Linux does a good job of making
temporary files go fast.

(GNU libc includes a memory-backed FILE*; see open_memstream...)

It's a shame that it's painful to get stdio and non-blocking IO to
work right together.
