Prevent reload_daemon from exiting.
* If a reboot stuck node fails, move the node to hwdown, send email, and log an entry in the nodelog. Then continue on. * If os_load fails, record the nodes that failed, and try again if the nodes fail to reload at the retry interval. Do not exit. I was going to call os_load again immediately, but decided not to since these changes were quite easy. The above change not really tested ... waiting for os_load to fail!
