[Sussex] linux process management

Hello All, I have a couple of questions:

1) How can you  "nohup" an an already running background job ( eg started with 
" myjob.sh &" ) so as to prevent it from being killed should the terminal 
hangup? (eg GPRS blackspot)

2) You have a process running via a ssh login session (eg /dev/pts/0) you then 
login (say when u get home) via ssh to tty /dev/pts/3 - how can you "move" 
the jobs running on /dev/pts/0 so that they are owned now by /dev/pts/3 (your 
current login session)?

I currently use nohup when i know a job will take some time and that i could 
be logged off before it finishes.

Sometimes I forget to nohup the job, sometime i am physically not in front of 
a terminal that's running a job.

What i would like to do is "take over" a process so that stdio is connected to 
my current tty.

Are there any specific commands that would perform this task - i guess some 
ioctl calls could implement this? if so does anyone have any pointers to 
relevent documentation?

Many thanks in advance
