+Summary: Mono consumes 100% CPU on raising events on Solaris
+
+This is may be related to the other solaris bug I have filed (79852).
+
+After our program does some memory intensive operation on Solaris e.g.
+loading a big XML document, when we raise events from a class, the CPU gets
+pegged at 100% for > 5 minutes before that event is raised. For example, in
+the example below, we see "before raise" and 5 minutes later we see "event
+received". This simple example works - but the same sample code in a big
+application breaks down as I have described above. Since I do not have mdb
+for Solaris, I tried using gdb - but I could not make head or tail out of
+it. If I single step in gdb, it seems to be continuously executing "wapi"
+code consuming 100% CPU.
+
+class foo {
+   public event EventHandler MyEvent;
+   public void FireEvent {
+      if (MyEvent != null) {
+         Console.WriteLine("before raise");
+         MyEvent(this, EventArgs.Empty);
+         Console.WriteLine("after raise");
+      }
+   }
+}
+
+class Receiver {
+    public void mmm {
+        foo x = new foo();
+        x.MyEvent += new ....... MyEventHandler;
+        x.FireEvent();
+    }
+
+    public void MyEventHandler(object sender, EventArgs e)
+    {
+        Console.WriteLine("event received");
+    }
+}
