I think this sentence from the essay gives the answer, at least from a 
security perspective:

 Probably the greatest cost of concurrency is that concurrency
 really is hard: The programming model, meaning the model
 in the programmer?s head that he needs to reason reliably
 about his program, is much harder than it is for sequential
 control flow.

We all know what hard programming tasks are likely to do to security...
