/*
 * In some error cases in our loadagent code we have no better course
 * of action available than to halt in a tight loop.  We define _exit()
 * to do the latter.  We have defined some codes for the argument value
 * that goes into R0; if you manage to hook up JTAG and get it to work,
 * you might be able to see what went wrong.
