Coverage.py measures itself on Precise Pandolin

From #python today, another report of this. Here's the "coverage debug sys":

veloutin reports that the files in /...2.7/dist-packages/ are symlinks to those in /..pyshared/

Turns out coverage is installed in an odd (?) way:

ned@ned-precise:/usr/lib/python2.7/dist-packages/coverage$ ls -l
total 212
lrwxrwxrwx 1 root root    47 Apr 23  2012 annotate.py -> ../../../../share/pyshared/coverage/annotate.py
-rw-r--r-- 1 root root  3198 Nov 22 21:16 annotate.pyc
lrwxrwxrwx 1 root root    47 Apr 23  2012 backward.py -> ../../../../share/pyshared/coverage/backward.py
-rw-r--r-- 1 root root  1590 Nov 22 21:16 backward.pyc
lrwxrwxrwx 1 root root    47 Apr 23  2012 bytecode.py -> ../../../../share/pyshared/coverage/bytecode.py
-rw-r--r-- 1 root root  3338 Nov 22 21:16 bytecode.pyc

This is fixed in <<changeset aae421baacfb28d240010c7ae7341698c0559b8a>>.
