Log Message:
	Use PTRACE_EVENT_EXEC to stop execution before return from execve(2).
	We can now verify that the arguments match what we accepted before
	the command actually runs.  If there is a mismatch, the process is
	killed.  Shell scripts must be handled specially since the path
	executed will be the interpreter, not the script name.
	Linux allows interpreters to be nested up to 4 deep.
