+ * Description: named semaphores for interprocess
+ * synchronization
+ *
+ * Unrelated processes obtain access to a shared semaphore
+ * by specifying its name.
+ *
+ * Our goal is to support named semaphores on at least
+ * Unix and Win32 platforms.  The implementation will use
+ * one of the three native semaphore APIs: POSIX, System V,
+ * and Win32.
+ *
+ * Because POSIX named semaphores have kernel persistence,
+ * we are forced to have a delete function in this API.
