The only thing that usually does this is the process being hung in the
kernel, e.g. it's stuck trying to access a device that's not responding.

Usually it's a device like a disk or tape drive, although years ago
SunOS 4.x had a bug where if the user used Control-S to suspend terminal
output then the process would be unkillable until they resumed with
Control-Q.
