This version basically works like the the previous, except that it makes
the priority adjustment faster (that is fine).
However I can fool it the same way.
"./a.out 7000"
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND

Fooling it:
"./a.out 7000 & ./a.out 6537 & ./a.out 6347 & ./a.out 5873 &"
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND

5504 paolo 18 0 2392 288 228 R 21.0 0.1 0:06.78 a.out
(priorities fluctuate between 18/19)
Again with more of them:
