Charles, I don't think you can blame autofs here. The problem at hand is that makedirs() never checks whether the directory exists (that would trigger the mount too I presume). Instead, it tries a mkdir and looks if it gets an EEXIST. If you try that approach in this case where /net is non-writable and /net/prodigy appears only on demand, it fails with an EPERM instead. Have a look at http://hg.python.org/cpython/file/8215aaccc9dd/Lib/os.py#l136 especially line 151.
