I redid the timings with mingw using time, and I find this strange

$ time ./test2.058.exe

real    0m55.500s
user    0m0.031s
sys     0m0.000s

If I know my time output, doesn't that mean the computer is 
spending 1 minute not running my program, maybe doing IO?

And 2.056 is similar, and actually takes longer in user time.

real    0m0.860s
user    0m0.047s
