Summary: os.popen with mode "rb" fails on Unix

Initial Comment:
On Windows, it's necessary to use the mode "rb" to 
open a binary stream to a process.  On Unix the "b" 
modifier isn't necessary, but supplying it causes the 
popen call to fail with 

   OSError: [Errno 22] Invalid argument

The Unix version of popen should accept and simply 
ignore the "b" modifier to the mode, rather than fail.  
That way the same code can run on both platforms 
without modification or extra code to special case an 
OS that may need the "b" modifier.
