What is free threading?

What happens if we need our Process to do more than 1 thing, like query a web service and write to a database at the same time. Luckily we can split a Process to share the time slice allocated to it. This is done by spawning new threads in the current Process. These extra threads ares sometimes called worker threads. These worker threads share the processes memory space that is isolated from all other Processes on the system. The concept of spawning new threads within the same process is called free threading.
