PROS
 - Now working for more than 2 processes.
 - uMax is getting higher from size 8 -> 16,
   but then is getting lower as the problem
   size grows.

CONS
 - Don't think it's working when a process has 2 collumns, needs more than 2.
 - Exists race conditions, in this commit there is a 'usleep()' to avoid crash
 - Also experiencing crash when finding uMax and/or freeing up memory
