The basic steps are: * Create a new task object to represent the address space. * Inspect the ELF binary you want to run and load the respective segments into this new address space. * Set up initial capabilities for the new task. These are necessary, so that the task has a memory manager, memory allocater, namespace etc. set. * Create a thread within the new task and let it run from the ELF binary's start address. There is a libloader that wraps most of this, especially the setup and binary loading part. Example users of libloader are pkg/moe, pkg/ned, and pkg/plr.
