Inquiry regarding the name of subprocess.Popen class

[Jeremy Banks]

Hi. I wondered if anyone knew the rationale behind the naming of the 
Popen class in the subprocess module. Popen sounds like the a suitable 
name for a function that created a subprocess, but the object itself is 
a subprocess, not a "popen". It seems that it would be more accurate to 
just name the class Subprocess, can anyone explain why this is not the 
case?

Thank you.
