zesarux: Double entries in history

[maziac]

Sometimes it seems as if zesarux would execute instructions twice or at least enter them into the history twice.

The same happens if calls are used instead of NOPs.
I.e. there are double entries for a call.

** HOW OFTEN:**
I checked 5x how often this occurs. After x instructions:
31712
31719
31724
31712
317124

I did the same with the NOP loop:
15417
15417
15417
15417
15417
This is more consistent.

double entries happen also without WPMEM being hit or even with WPMEM completely disabled (-14,-15):

So the main problem are the double entries itself. That the read mem breakpoint is fired seems to be a side effect.
