Are you sure pari_unique_dir() is racy ?

Maybe we should fix get_file not to be racy.
We should remove fix pari_unique_dir/pari_unique_filename.
pari_unique_filename is only used to implement pip on DOS EMX which will not
be missed.

pari_unique_dir could be replaced by pari_create_unique_dir() which create the
directory (I think it is already the case though).

Cheers,
