Use schedule bounding as the primary SCT approach.
...
This allows results to be naturally reported as lazy trees, rather
than as lists representing a tree traversal. This in turn means
that the actual bound can be moved outwards to the testing code, and
not used at all in the runner. Trees let us do nice things with
shrinking and short-circuiting, if we make the (fairly reasonable)
assumption that the children of a buggy result will exhibit the same
bug.
Storing results as trees does complicate the predicate helper
functions somewhat, but I think the clarity gained in the actual
SCT code is well worth it.

Report 2 capabilities for test runners, not 4.
...
The literature sttes that many bugs are found with 2 concurrent
threads, so encouraging even more parallelism is possibly a win in
only a small number of cases, but potentially a huge cost in many.
