# whatever, jhass

# the point of this was to print a prime number but to take five seconds
# the idea was that you would compute it very slowly
# you cant use sleep

# my thought was to attach a block to time so that it ran each second
# and then just print a prime on every second divisible by five

# i feel like a pussy for not having ever completed this
# and i wonder...
# what if I just had a busy loop with a counter that counted
# how long it had been since it last yielded to some &block or something like that?
