- * The custom implementation of the CPU session interface is used to tweak
- * the startup procedure as performed by the 'Process' class. Normally,
- * processes start execution immediately at creation time at the ELF entry
- * point. For implementing fork semantics, however, this default behavior
- * does not work. Instead, we need to defer the start of the main thread
- * until we have finished copying the address space of the forking process.
- * Furthermore, we need to start the main thread at a custom trampoline
- * function rather than at the ELF entry point. Those customizations are
- * possible by wrapping core's CPU service.
