single-stepping code is messy now -- applications have to copy the skeleton from app/bench/main.c and directly use libsgxstep's low-level apic and page table manipulations to build the single-stepping primitive each time in the attack application.
Instead, libsgxstep should offer a convenient start/stop_single_step() abstraction that encapsulates all of the low-level details and platform-specific code. At this point we could also take care to enable/disable the APIC timer and pin to a specific CPU core etc.
