The tests I did so far, thinkpad x230 with HT enabled and hw.smt=0:

glibtop_get_cpu() from libgtop2 is broken, I get an abort due to
a double-free error when using the short program below.
--8<--
// cc -g $(pkg-config --cflags libgtop-2.0) gtop2.c $(pkg-config --libs

int
main(void)
{
glibtop_cpu gcpu;
glibtop_get_cpu(&gcpu);
return 0;

Looking at the code, uv_cpu_info() will now fail (but at least it
shouldn't crash). dunno how many ports actually use it.

py-psutil is completely broken, ''import psutil'' fails:

>>> import psutil

Both the libgtop2 and the py-psutil problems are fixed with hw.smt=1.
