Correction for the fix for Bug 3508 - Persistent storage support breaks Linux compatibility.
A 2nd `make install' will fail attempting to create symlink libnvmemmory.so already created by 1st install.
Install should pre-emptively delete it.
This is a sample doctest in a text file.
In this example, we'll rely on a global variable being set for us
already:
>>> favorite_color
'blue'
We can make this fail by disabling the blank-line feature.
>>> if 1:
... print 'a'
... print
... print 'b'
a
<BLANKLINE>
b
