Huh? I'm somewhat confused now. Something in the plasmoid obviously was
broken, and made Tim's plasma hang.
And this is a problem that happens regularly when trying custom
plasmoids.

I don't say the non-blocking download is blocking. It's something in the
plasmoid, whatever it may be. And as the result, all of plasma hangs.
Which is bad.

Yes, but I was talking about cooperative multitasking. Long ago, like in
Windows 3.x, where a single application could make the whole system hang.

No, I was just saying that the individual plasmoids seem to use
cooperative multitasking. A badly designed, hanging plasmoid makes whole
plasma hang. Other processes are not affected, of course. So you can
continue to work, but as Tim wrote, many people will just think the
system is hanging, and reboot.
