assuming python must initially use getcwd() internally to do this, and then
if that fails it falls back on something else. but what is that something
else? is it something that is reproducible in pure python?
I would think that the OS system call, not Python itself, does the
relative->absolute conversion.
so there is a discrepancy between some of the std library path functions
(like realpath, getcwd, abspath) and the built-in open function. there
are files which can be opened for which it is impossible to resolve
their full paths (on some platforms).
