Properly implement sleep sets.
...
- Don't make decisions in bporSched which are in the sleep set.
- Don't consider backtracking points from executions which terminated
due to every decision being in the sleep set.

Don't pre-empt thread termination with exceptions.
...
If a thread is about to terminate gracefully, there's no point in
pre-empting the `Stop` action to throw an exception to it.

Introduce a dependency between the final action and everything.
...
Introducing length bounding failed to find a deadlock in the Dining
Philosophers! I believe that the typical DPOR algorithm assumes that
every thread terminates before the entire process terminates, which
simply isn't the case in Haskell.
To combat this, a dependency was introduced between the final action
in a trace and everything. Just introducing a dependency for (0, Stop)
isn't enough, as execution can be aborted due to the length bound on
any action.
