If you have native tasking then tasks are as fat as threads. If you have
tasking implemented within one thread (rare), tasks can be "micro", but
then they most likely will be unable to perform I/O concurrently.

It is not that simple. The problem space may encompass the hardware, e.g.
in the case of communication and services. Which is typically the case when
worker tasks pool comes in question.
