Jochen Liedtke's untimely death really set back OS design.

The abnormal termination of a single process really shouldn't have been able to take down the whole system like that.

Actually, L4 is so tiny that Liedtke called it a "nanokernel". It would probably qualify as a hypervisor today.

Liedtke was running multiple instances of Linux side by side with L4 "native" apps in the late 1990's with only a 3-5% performance degradation.

Damn cool stuff, and the L4 core was only a couple thousand lines of code if memory serves.
