Exclude current directory from import by changing directory
Exclude current directory from import by changing directory

The issue is that with multi-processing, new process are spawn and
`import pythran` resolve in the current directory. The solution
is then to change the current directory so that the new processes
won't find pythran here but will use the PYTHONPATH
