/* Ballhausen's solution to classical reader-writers fairness problem */
/* Initial problem : a continual flow of readers blocks writers from updating */
/* Ballhausen's solution :
 *  * one readers takes up the same space as all readers reading together
 *  * a semaphore access_db is used by readers to enter the database with a
 *    an initial value equalling the number of readers
 *  * every time a reader is accessing the db, the semaphore value is
 *    decremented
 *  * every time a reader is leaving the db, the semaphore value is incremented
 *  * writers want exclusive access to the db. It occupies all spaces step by
