Glad you solved it and using subprocess is fine for the pmap stuff.
But the grep and awk stuff are usually a lot faster and almost as
easy using Python.

eg.

for line in pmap_output
     if private in line:
        print line.split()[0]    # {print $1}

Or, to create a list instead of printing

col1 = [line.split()[0] for line in pmap_output if private in line]

I can't remember what -FK does (F is field sep but K?)
But I'm fairly sure it will be easy to replicate in Python.
