Yes, it's come up for discussion several times... I don't like the
current behavior either. The current behavior was added many years
ago for an unspecified application :-(

/* Decide if the current function is volatile. Such functions
never return, and many memory cycles can be saved by not storing
register values that will never be needed again. This optimization
was added to speed up context switching in a kernel application. */

IMO that shouldn't be written in C, then...
