Good article, also has references to the glib's source. I've never dived deep into the random() system function before. This is from the man pages:

"The random() function should not be used in multithreaded programs where reproducible behavior is required. Use random_r(3) for that purpose."

Perhaps the notes should be updated to state that the performance of multi-threaded programs is also affected due to the shared global resource?
