This is bad: parallel tests are fine for tiny tests which use only a little bit of memory. However if your tests are very large and use a lot of RAM then running them in parallel can cause them to fail unnecessarily. The libguestfs test suite is exactly like this: parallel tests causes it to fail because you end up running multiple parallel VMs. Serial tests is the right way to go for us.

We should say that 'paralle-tests' is "encouraged", rather than saying that 'serial-tests' is "deprecated". In fact, there are no plan to ever remove it, or even give runtime warnings upon its usage.
