Comment:

 Fantastic, thanks! Pushed with some
 [https://gitweb.torproject.org/stem.git/commitdiff/4b980915168e3c712e7352c81c9c00671da7a075
 minor tweaks]. I'm surprised and a tad sad isinstance() isn't more
 performant. It should be a simple comparison of the class attribute...

 {{{
 >>> def my_isinstance(v, c):
 ...   return type(v) == c
 ...
 >>> my_isinstance('hello', str)
 True
 }}}

 ... or...

 {{{
 >>> def my_isinstance(v, c):
 ...   return v.__class__ == c
 ...
 >>> my_isinstance('hello', str)
 True
 }}}

 It made for slightly friendlier code. Are you sure dropping isinstance()
 had a substantial impact?

 If it did then there's a few other isinstance() calls in
 [https://gitweb.torproject.org/stem.git/blob/HEAD:/stem/util/str_tools.py
 str_tools].
