-  a method to make semaphores less error prone. The WITH_SEMAPHORE()
-  macro will block forever for a semaphore, and will automatically
-  release the semaphore when it goes out of scope
-
-  Note that we have two types of semaphores. A normal semaphore can
-  only be taken once. A recursive semaphore allows for the thread
-  holding the semaphore to take it again. It must be released the same
-  number of times it is taken.
-
-  The WITH_SEMAPHORE() macro can be used with either type of semaphore
