There is a tendency of sharply rising CPU loads, now at extreme level

[TCH68k]

I've made some measuring about CPU loads. I've built all puNES releases from 0.106 (earlier ones failed to build now) to 0.111 (except for 0.108, which also failed to build), plus the latest development version of 0.112. puNES is eating more and more resources; the rising in CPU load is alarming.

Here is a table for illustration:

Version	Size (CLang)	Size (GCC)	Load (CLang)	Load (GCC)	Fans
0.106	1402K	1402K	50% / 40%	50% / 40%	Silent.
0.107	1498K	1497K	50% / 40%	50% / 40%	Silent.
0.109	1730K	1733K	70% / 40%	70% / 40%	Silent.
0.110	2966K	3257K	87.5% / 55%	85% / 52.5%	Bit louder, occasionally spinning up more.
0.111	4094K	4443K	110% / 80%	115% / 85%	Loud, spinning fast, continously.
0.112	4103K	4454K	112.5% / 80%	112.5% / 82.5%	Loud, spinning fast, continously.

Measured with htop, the settings, the build options and the environment were all the same.

Something started to going wrong after 0.109 and it got worse. If someone gives me advice about how can i measure what parts are consuming this much, i will do it.
