 // An event is a synchronization object whose state can be set and reset
 // indicating that an event has occured. It is used pervasively throughout
 // the GC.
+//
+// Note that GCEvent deliberately leaks its contents by not having a non-trivial destructor.
+// This is by design; since all uses of GCEvent have static lifetime, their destructors
+// are run on process exit, potentially concurrently with other threads that may still be
+// operating on the static event. To avoid these sorts of unsafety, GCEvent chooses to
+// not have a destructor at all. The cost of this is leaking a small amount of memory, but
+// this is not a problem since a majority of the uses of GCEvent are static. See CoreCLR#11111
+// for more details on the hazards of static destructors.
