Sorry, I need to recommend against my patch. It seems to break the
debugger. :( I'd still like to see the exec stack issue fixed. Forcing
exec stack for all mono apps seems... unfun. ;)
$ echo 'class MainClass { static void Main() { System.Console.WriteLine("Hello
World!"); } }' > hello.cs
$ gmcs hello.cs
$ ./hello.exe
Hello World!
$ mdb ./hello.exe

A good run would be:
