+Summary: Process start code can try to execute directories
+
+The Start_internall icall for the Process.Start code will sometimes try to
+execute a directory in the right conditions. 
+
+When running with a relative pathname and UseShellExecute = false, the code
+will search for the executable in PWD. If it finds a file with the execute
+bit it will run it; however the code doesn't check if the file is regular.
+For a demonstration, use the attached demo.cs.
+
+$ mcs demo.cs
+$ mono demo.exe
+[works]
+$ mkdir ls
+$ mono demo.exe
+[bomb]
+
+I will attach a workaround patch. The CreateProcess() function in io-layer
+seems like it might have similar issues, but just the patch that I have is
+enough to avoid this particular problem.
