        very inefficient for the list: [1,2,3,9999999999]

        Even for [1, 2, 3] is inefficient.

        Is it only me who is irritated by the fact that "element" and "X" are never identified with each other in the algorithm? :P

        No. Looked at it and asked 'who the hell is X?' Took me several seconds to realize X is each element.

        I have an idea to make it faster. Change second to microsecond

        As sorting algorithms go, the one described here is a really bad one. For one, it relies on a another algorithm to sort the wake up times. Second, timers on most computers have a resolution of about 50 milliseconds, so the sort would be quite inaccurate on top of being slow.

        Interesting need for parallelism. The following will complete the sort sooner by a factor of N. (With some conditions on N such that the smallest element X(0)/N and [X(i+1) - X(i)]/N > duration of handling 1 & 2 otherwise errors may occur. 1. Sleep X/N seconds 2. Prints X

        high potential for numerical error if max(list) is large
