Presumably it's somehow related to memory? What would
sudo cat /dev/urandom > /dev/mem
do? Trash all RAM? All non-kernel virtual memory? None of the above?

It provides access to the system's physical memory. Here's some more info on what /dev/mem is. Yes -- it could cause all sorts of problems. A reboot should fix you, but bad things can happen very easily. Be careful! :-) | |||||

/dev/mem provides access to system physical memory, not virtual. The kernels virtual address space can be accessed using /dev/kmem. It's primarily used to access IO memory addresses related to peripheral hardware, like video adaptors. | |||
