I'd recommend using screen to run jobs "in background". You can always 
get back to detached
screen session and have access to previous state of shell(s).
Although much better solution is to run some kind of queuing system, 
like PBS or SGE, which
gives you possibility to put many jobs in queue and go on vacation being 
sure that jobs are being
run one after other.
