I suppose that makes sense on an OS on which crashing is expected behaviour, though some people would want to know what bug caused the crash and whether that bug has security implications.
The Linux kernel doesn't crash much, unless you have dodgy drivers or dodgy hardware. Whether your userland programs crash or not depends on what you're running. I don't expect to see sshd crashing, for example, though it's true that almost any program will exit suddenly if the system runs out of memory, which to an ordinary user looks like a crash, though it's a very different thing really.
There is, of course, absolutely no difference in how errors are handled in this case vs forks. A process that handles one million requests is much more likely to crash than a process that handles one request though (regardless of OS).
