chained beforeAll()s fail

[fschwiet]

this should work:

        var store = beforeAll(() =>
        {
            return new EmbeddableDocumentStore()
            {
                RunInMemory = true
            };   
        });

        var process = beforeAll(() =>
        {
            store.Initialize();
            ...
        });

This failed, store was null in the second beforeAll block.

PerFixtureSetupContext

• prepares to run spec on external thread, blocking on a test request.
• on test requested (by position), unblocks the thread and starts running.
• the spec visitor will be in one of two states, depending on whether the current test positoin leads to the desired test.

visitor states:

"Forward" "current spec position leads to the requested test"

• runs beforeAll, making result available
• queues afterAll
• on describe block, may switch to state "Retreat"
• on targeted test, blocks.

"Retreat" "current spec position does not lead to the requested test"

• skips beforeAll, afterall
• on exiting block, runs queued cleanup
• on exiting block, may switch to state "Forward"

outer thread calling spec will restart spec whenever it finishes, until told to shut down

external callers needing to cleanup/stop the thread will set a null requested test, then wait on the thread to finish.
