+Summary: Accept in Socket code has a race condition.
+
+While running the Mono XSP.EXE server and trying to debug it, I get the
+following error, you have to run this twice.   I get an InvalidArguments.
+
+Now, if I try to strace the problem, the program works;  If I run it with
+--trace, the program fails.  So my guess is that there is some race
+condition.  There are no threads involved.
+
+mono$ mono server.exe  9001
+Remember that you should rerun the server if you change
+the aspx file!
+Server started.
