+// Date: 1998-02-19
+// Description:
+// tests scheduler & threads & priorities
+// + create multiple threads with various priorities
+// + check highest priority running thread is always running
+// + check next highest runs when highest suspended
+// + check several threads of equal priority share time
+// (only !CYGINT_KERNEL_SCHEDULER_UNIQUE_PRIORITIES)
+// + check other threads are starved
+// + check setting priority dynamically causes a thread to
+// become/stay current/non-current
+// Omissions:
+// check yield
+// check can set threads with min and max priority
+// Options:
+// CYGINT_KERNEL_SCHEDULER_UNIQUE_PRIORITIES
+// CYGIMP_THREAD_PRIORITY
+// CYGNUM_KERNEL_SCHED_PRIORITIES
+// CYGSEM_KERNEL_SCHED_BITMAP
+// CYGSEM_KERNEL_SCHED_MLQUEUE
