Well this would definitely be a '''user error'''. You can always set
`DOT_SAGE` or `SAGE_TESTDIR` (or whatever it is called) if you want to run
multiple tests simultaneously in different shells, even in / with the
''same'' Sage installation.
> They need to be unique for any number of instances of Sage. I think
testing under $HOME/.sage is a bit silly myself - it would be better to
test under the directory where Sage is installed.
Definitely not, since this wouldn't work for site installations, where
users usually have no write permissions under `SAGE_ROOT`.

good if it could.
One could use Sage's PID, user and machine parameters etc. to try to
create unique directories, or generally create "random" directories with
`mktemp (1)` or `mkdtemp()`, but I think this would be an overkill, since
the user can itself do such by setting one of the above variables.
