//SynchronizedAfterSuite blocks complement the SynchronizedBeforeSuite blocks in solving the problem of setting up
//external singleton resources shared across nodes when running tests in parallel.
//
//SynchronizedAfterSuite accomplishes this by taking *two* function arguments.  The first runs on all nodes.  The second runs only on parallel node #1
//and *only* after all other nodes have finished and exited.  This ensures that node 1, and any resources it is running, remain alive until
//all other nodes are finished.
//
//Both functions have the same signature: either func() or func(done Done) to run asynchronously.
//
//Here's a pseudo-code example that complements that given in SynchronizedBeforeSuite.  Here, SynchronizedAfterSuite is used to tear down the shared database
//only after all nodes have finished:

//if the panic originates in a Ginkgo node (an It, BeforeEach, etc...)
//
//Unfortunately, if a panic originates on a goroutine *launched* from one of these nodes there's no
