Summary: Potential error concealment in COM server initialization

Initial Comment:
file win32com\server\policy.py 
class BasicWrapPolicy:
  def _CreateInstance_(self, clsid, reqIID)

this function brings some danger in case of 
win32api.error raise from server initialization routine. 
I'd suggest to move except statement some rows above to
except only CLSID/PythonCom key reading failure.

I don't quite follow this.  Object creation should be in the
code:

  if dispatcher:
    retObj = dispatcher(policy, None)
  else:
    retObj = policy(None)
  return retObj._CreateInstance_(clsid, reqIID)

And this is not wrapped in an except handler.  I guess that
getting the dispatcher class could fail, but that seems alot
less likely than the class constructor failing.

Can you please give me a real example of what could fail?
