Is it possible to save a running program and reload next time ?

This isn't what you asked for (I have no idea how to do that), but
given your description, perhaps a different solution would work.

If you're using a *nix type OS (or possibly Cygwin, never tried) with a
bash-style shell, then you probably already have job control built in.
For example, in bash you can type <CTRL>Z to stop the current process,
and you can see all jobs and their states and job numbers with the
'job' command, and you can resume a stopped job with '%[job_number]'.
So for example, if only one job is in he queue, just stop it and then
when you're ready do %1.

Another *nix option would be to use the nice command to set the
schedular priority of the process so that when something with a higher
priority needs the CPU then it gets it first rather than your nice'd
process (something like 'nice -n 15 python your_program.py' should do
well -- very low priority). I'm pretty sure windows has some kind of
priority option for tasks as well, in fact, IIRC you open the task
manager and right click on a task and can set the priority lower.
