Race condition on uninstall when setup.py develop is used

[schlamar]

Steps to reproduce

1. Install a package
2. Install the same package from source with python setup.py develop
3. Uninstall package with pip

Expected behavior: package is removed

Actual behavior: only develop egg-link gets removed, original install from 1. remains.

Example output

$ pip uninstall pytest-cov
Uninstalling pytest-cov:
  c:\python27\lib\site-packages\pytest-cov.egg-link
Proceed (y/n)? y
  Successfully uninstalled pytest-cov

$ pip uninstall pytest-cov
Uninstalling pytest-cov:
  c:\python27\lib\site-packages\pytest_cov-1.6-py2.7.egg-info
  c:\python27\lib\site-packages\pytest_cov.py
  c:\python27\lib\site-packages\pytest_cov.pyc
Proceed (y/n)? y
  Successfully uninstalled pytest-cov

Somehow related is issue #1552 although it's for pip install -e not setup.py develop directly.

This has been fixed and is no longer the case.
