+TargetMilestone: ---
+Summary: CreateThread failure/out of wapi handles slots
+After running mod-mono-server for a couple of hours, the runtime
+starts to spill the following output:
+** (/opt/mono/lib/xsp/1.0/mod-mono-server.exe:260): WARNING **:
+CreateThread: error creating thread handle
+Unhandled Exception: System.ExecutionEngineException: Couldn't create thread
+in <0x00000> <unknown method>
+in (wrapper delegate-begin-invoke)
+in <0x00014> System.Threading.ThreadPool:QueueUserWorkItem
+tCallback callback)
+in <0x00273> Mono.WebServer.ApplicationServer:RunServer ()
+in (wrapper delegate-invoke) System.MulticastDelegate:invoke_void ()
+** (/opt/mono/lib/xsp/1.0/mod-mono-server.exe:31027): WARNING **:
+thread_attach: error creating thread handle
+"ps" doesn't show more than 10 threads for the process. The
+server is almost idle and it manages to serve about 15-30K requests
+until the error occurred.
+I'm attaching the output of "hps" which lists a lot of threads
+being in the THREAD_TERMINATE state.
+Mono version: head of the 1-1-13 branch
