I've not dug deeply into the Kindle OS, but it's my understanding that all programs are running as the root user, which means that they have a little more ability to trash things, though spontaneous reboots are usually not caused by problems in programs running in user-space, even as root. More likely there are bugs in the display driver or input driver that run in a ring closer to the kernel than user-space programs, with fewer protections. It's also entirely possible [though complete speculation] that Amazon has modified the kernel itself and runs Kindle specific things in ring 0 which is basically completely unprotected.
