Summary:
 DRT protocol needs non-blocking file read.
 Windows Python (non-Cygwin) can't set non-blocking mode by fcntl().
 Cygwin Python can do it.


Possible solutions:
 a) Use Cygwin Python
  I tried it.  I needed some cygpath conversion hacks, but still have mysterious hangup.
 b) Use ctypes
  Can we use ReadFileEx() through ctypes.windll.kernel32?
 c) Implement test_shell protocol for Chromium DRT
