There is no real drain on resources when rendering and plenty
of free memory. I wonder if it's specific to the windows version,
possibly OS memory allocation is less efficient when allocating
gazillions of tiny blocks there?

I now watched the behavior in the task manager:

Before rendering: 40 MB

After rendering: 200 MB (after about 1 second)

While "hanging": Memory usage slowly decreases but
at ever-increasing speed, when reaching 40MB after
about 20 seconds GUI goes "Ping".
