+Summary: NullReference exception in WaitOne()
+I'm seeing intermittent failures (once every few thousand calls) on a call
+to WaitOne() with RedHat 8, dual processor machine:
+System.NullReferenceException: Object reference not set to an instance of
+an object
+in (unmanaged) (wrapper managed-to-native)
+System.Threading.WaitHandle:WaitOne_internal (intptr,int,bool)
+in <0x00004> (wrapper managed-to-native)
+System.Threading.WaitHandle:WaitOne_internal (intptr,int,bool)
+in <0x00088> (wrapper remoting-invoke-with-check)
+System.Threading.WaitHandle:WaitOne_internal (intptr,int,bool)
+in [0x0000f] (at
+System.Threading.WaitHandle:WaitOne ()
+in [0x00007] (at /home/michi/src/icecs/src/Ice/BasicStream.cs:1869)
+IceInternal.BasicStream:getUserExceptionFactory (string)
+in [0x00015] (at /home/michi/src/icecs/src/Ice/BasicStream.cs:1320)
+IceInternal.BasicStream:throwException ()
+The corresponding code is very simple, and runs fine with the .NET run
+time. (It works fine when compiled with either Visual C# or mcs.)
