I do not think you can read while a file is being written to.  For
example, I ran a program that is in an infinite loop that prints Foo,
sleeps for 10 seconds, then prints Bar.  I redirected the output to
log.txt.  I opened the txt file each time, and saw nothing on the text
file.  When I abnormally closed the program, the text file had all the
output.
