 higan is therefore very cautious about timing:
-it always checks all possible devices
-to see if anyone wants to interrupt anyone else
-before proceeding to the next emulated step.
-Although repeated checking is slow,
-higan checks anyway
+while it's emulating the audio chip (for example),
+at every point the emulated CPU *might* interrupt
+the emulated audio chip,
+higan switches to emulating the CPU up to the same point
+to find out whether the CPU *will* interrupt it.
+
+In this way,
+higan is a little bit like
+an office-worker trying to do the jobs of three other people
+by running from desk to desk,
+sending the same emails
+that those three people would send to each other,
+leaving themselves a note at each desk to remind themselves
+where they were up to when they come back.
+Although this constant switching
+is slow and inefficient,
+higan does it
 to ensure the emulated console
 always matches the behaviour
 of the original.
