Happiness overflow

[anshukla]

happy1.c has concerning potential for happiness overflow. Some sensible solutions if we've attained maximum happiness:

• Stop and enjoy this state of enlightenment
• Fork children that partition our happiness so they can increase total happiness

Unfortunately, due to the known "hedonic treadmill" bug, it may be impossible to stop and enjoy a high state of enlightenment. I believe a better solution is to use 64-bit or arbitrary-precision integers to continue running on the treadmill indefinitely.
