Random seed not released (mac only?)

HI, I had a problem when running the examples that there were too many dev/random clients run, and I tracked it to the function sc2common, maybe only on mac since it hasn't been reported? . I corrected it and seem to be running fine, but I am not too familiar with git so can someone help me to code review and commit the code, or find a better solution since I'm not an expert in programming =) Thank you in advance.

git diff ->

+class RandomGeneratorClass{
+ public: RandomGenerator* getNextGenerator(){
+ ++currentGenerator > NUMBER_OF_RANDOM_GENERATORS-1 ? currentGenerator = 0 : NULL;

+ randomGenerators[currentGenerator] = new RandomGenerator();
