lockingTextWriter wraps stdout (or any other file) with an OutputRange 
that locks the file while writing.  This ensures that thread-shared files 
(which stdout is) don't accidentally interleave; if you write a line, 
you'll get the same line unbroken in your output, even if other threads 
are trying to write to stdout.
