To anyone who might not be familiar with the applications of timelike paths in computers: it's the quickest way to the singularity. Basically, you get a computer and wire its output (in the future) to its input (in the present or past). Depending on how time travel works, this either gives you an infinite amount of computational power (actually an infinite amount of time to perform operations in, but it looks rather similar to outside viewers) or a way to quickly find the conditions under which a program returns the input as output (which gives you instantaneous protein folding, factoring of large primes, and so on, if you design your programs properly. If you don't, it gives you a good way to find buffer overflows and other failure conditions). Of course, both of those would look pretty much exactly the same to outside viewers.
