What I hate about *Unit frameworks.

Most of them invest way too much effort to make up for the deficiencies of
the Windows Operating system.

The Component in a Computer tasked with managing concurrency, task
separation, and ensuring full clean setup and tear down is....

The Operating System.

So if you want to be dead, 100% sure that this test doesn't corrupt that
test... you use a process.

Nope, not try / catch, not exception handling. That's a flaky almost
solution.

One test === One Process.

Each process is an address space that appears.... and vanishes.

But, but, but Processes Are HeavyWeight you can't create and run thousands
of processes!

Oh yes you can.

Processes are lightweight under Unix and have been for decades.

In fact much of the hype about threads is a result of Microsoft marketing
spin to cope with the fact that Windows 3.1 processes were incredibly
heavyweight kludges.

In fact there are relatively few places where one should use threads when
one can use processes.

Want to run a thousand tests? Well, how many cores do you have? Let's keep
every core 100% busy. One test, one core.

But who is going to spin all those processes and mind the result?

GNU parallel is a pretty nifty choice.

Or maybe it is something the xUnit's should be doing.
