Load Eboot from usermode and controlling it

See the sdk provide with the 4.01M33 firmware there is a sample to launch
a cso,iso,ps1 game from a shell program when the program end it comes back
to your shell.

ok now i got it to load an eboot and come back too it but i was wondering using the bootload sample can some explain how it works like does the original game where the second game was launched stay in memory or exit and will it crash the psp if the original one was using alot of memory
also how can i restart the game and have it come back to it or shutdown the psp and have it come back to the game
