Summary: zipimport on meta_path fails with mutual importers

Initial Comment:
If I create a simple package consisting of a
package/__init__.py containing:
  print "Package: "+__name__
  import module

and a package/module.py containing:
  print "Module: "+__name__
  import package

and zip the directory resulting directory up, then it
imports fine if I add the zip to sys.path

However if Instead create a zipimporter object and add
it to the meta_path then I get a whole heap of
recursive imports resulting in  output of the following
form:
Package: package
Module: package.module
Package: package.package
Module: package.package.module
Package: package.package.package
Module: package.package.package.module
Package: package.package.package.package
Module: package.package.package.package.module
Package: package.package.package.package.package
....
before finally running into an exception:
ValueError: Module name too long

For reference my version string is '2.3 (#46, Jul 29
2003, 18:54:32) [MSC v.1200 32 bit (Intel)]'
