A learning exercise but pretty useless otherwise. As others pointed out, 
immediately stripping off \n is a bug relative to *your* function 
description. Also, you yourself then give an example of joining with \n. 
But that does not restore the final \n. The rest duplicates the 
iteration ability of the .stdout file object.

For repeated execution of code like
   process.stdout.readline()
you can once create a 'packetized' bound method object like so
   cmdline = process.stdout.readline
and then, without repeating the attribute lookups, repeatedly call
   cmdline()
.
