Comment(by gmorehouse):

 I am occasionally seeing some exception spew in between refreshes that
 contains the text 'lsof is unavailable.'

 Got any quick URLs I could use to learn how to profile 'arm' in a quick
 and dirty way to see what it's shelling out to?

 Also, are there common (eg POSIX) system calls that are wrapped/usable in
 Python that are the equivalent of querying /proc for the information you
 need?  /proc is pretty Linux-specific.  I'd think system calls would be
 just as fast if not faster, and maybe more portable, but I'm unsure what
 information you're reading.
