Travis, can you check to see if this is still a problem and decide if it's
worth our while to try to do something about it?

> rw_putenv() uses putenv() to add variables to the environment. Unfortunately
> putenv() actually places the user provided string into the environment, so
> the string cannot be deallocated immediately. The result is false positive
> memory leaks in tests that use rw_putenv().
> One solution would be to use setenv() and unsetenv() on platforms that
> support them. This avoids the memory leak. Another option would be to have
> rw_putenv() track the environment strings that were added, then remove and
> deallocate them when the test driver is taken down.
