An alt-stack and interrupt-handler are added to ikarus-main.c. When
an interrupt occurs, the engine_ticks is set to 1 and the
interrupted field is set to 1 in the pcb.

Actually, the profiling times show that memory-based tests can be
performed at around 3 secs per 1 billion checks (about 6 times
slower than register-based counters).

Profiling timing shows that we can do interrupt checks with cost:
* about 2.0 secs per 1 billion checks if the counter is kept in memory
* about 0.5 secs per 1 billion checks if the counter is kept in register.
