+Summary: [PPC] XSP has a jit bug which causes failures
+Running xsp / mod_mono on HEAD is currently failing due to a jit bug.
+I believe this is a similar one to the last stack (un)winding.  The call that is being improperly 
+handled is in XSPApplicationHost.cs:
+public void ProcessRequest (int reqId, long localEPAddr, int localEPPort, long remoteEPAdds,
+                                        int remoteEPPort, string verb, string path, string pathInfo,
+                                        string queryString, string protocol, byte [] inputBuffer, string redirect)
+which is called from: XSPApplicationHost.cs:210.
+I have modified this call locally to be:
+host.ProcessRequest (requestId, this, rdata, redirect);
+with the call signature:
+public void ProcessRequest (int reqId, XSPWorker worker, RequestData rdata, string redirect)
+This modification masks the JIT bug.
+To replicate, run xsp/mod_mono from CVS HEAD, with mono from CVS HEAD and request the 
+session1.aspx test.  Submit the callback a few times and you will get an exception.
+I'm going to work more on atomicizing a cross-appdomain call that can replicate the same 
+behaviour but have been unsuccesful so far..
