<Purpose>
When an internal error happens in repy it should be handled differently
than normal exceptions, because internal errors could possibly lead to
security vulnerabilities if we aren't careful. Therefore when an internal
error occurs, we will not return control to the user's program. Instead
we will log the error to the service log if available, then terminate.
<Arguments>
error_string - The error string to be logged if logging is enabled.
exitcode - The exit code to be used in the harshexit call.
<Exceptions>
None
<Side Effects>
The program will exit.
<Return>
Shouldn't return because harshexit will always be called.
