[BangPypers] psphere: how to make thread safe

[Saju M]

Hi,

psphere: Python interface for the VMware vSphere Web Services SDK

I already developed an app using https://bitbucket.org/jkinred/psphere. But
getting lot of errors since psphere is not thread safe (I think). So i
wrote couple of scripts to test it (See attached files) and found that
caching mechanism used by psphere is not thread safe. Could someone please
give me some suggestion to make it thread safe.
