Well, perhaps an indication that this is not Windoze! ;-)
The Linux kernel doesn't expect to be generating exceptions itself, so it
always blames the threads that trigger them. Or; Linux doesn't pretend to be
fault tolerant WRT kernel bugs. (It's stupid to even try that if you care the
slightest about security; only true microkernels can provide anything like fault
tolerance against driver bugs, and that's only for hardware not using DMA...)
