If you are talking about simple multi-threading with singleton then there will be no issue untill a resource is not freed another thread doesn't accquire it. Also, multi-threading doesn't mean parallel execution, most of the time only one core of the system handles the task, Multi-threading just do time slicing.
TPL is real parallelizm.

also, singleton with multi threading may lead to double-checked-locking.
