How is it possible for one thread to read the size of a file while
another thread is still writing to it? This runs into sharing I/O
errors.

What makes you think the OS should allow that at all? That said, if
the writing process set the right sharing flags, it should be possible
on at least some filesystems.

Better to ask the other thread how many bytes it's written.

Or let the other thread tell you without being asked.

Personally I would break this into two different Apps
- I am wary of threads
.
