Load a new far_entry_point program for every new session?

[restart-again]

Hi, Thanks for your wonderful code and sharing. In my understanding, from your code, whenever a session coming, a new far_entry_point program and data will be loaded to the kernal.
I am wondering why we can't use the same program but give new session data to the far_entry_point program. I suppose the whole far_entry_point program is much larger than the data, and the kenerl may can not accomodate too much programs, one copy of the code should be enough, why need to load different code copies for every session? I am not very familiar with BPF yet, please feel free to correct me, thanks.
