There was a window between the write and the chmod where the user’s
password would be exposed, depending on default permissions.  Philip
Jenvey’s patch fixes it.

These files are created by some NFS clients a file is edited and removed
concurrently (see added link in doc for more info).  If such a file is
removed between distutils calls listdir and copy, it will get confused.
Other special files are ignored in sdist (namely VCS directories), but
this has to be filtered out earlier.
