Gavin Mak 3e6acf2778 progress: Fix race condition causing fileno crash ...

A race condition occurs when sync redirects sys.stderr to capture worker output, while a background progress thread simultaneously calls fileno() on it. This causes an io.UnsupportedOperation error. Fix by caching the original sys.stderr for all progress bar IO.
