Disabling interrupts will certainly provide an atomic operation. However I
don't wish to stop all other interrupts. I only wish to stop one particular
interrupt while executing a section of code. To disable all interrupts (or
all to a certain priority level) seems like such a waste! I would like to
reduce interrupt latencies as much as possible so any disabling of
interrupts will affect the ability to respond quickly.
