I’ve been running some more tests over the weekend. At 32 I still get quite a bit of racy
behaviour, and at 16 it looks roughly the same as an x86 run.
So yes, 16 sounds good.

All looks good.
I’m not sure who gets access to the wiki (looks like I can’t log in).
Errors I noticed:
* There is a mention of both 0.8.14 and 0.8.12 for buildslave
* The Debian specific instructions should probably also be for Ubuntu too.

That’s fine.

Nope. My usual build line is:
$ configure --enable-sim --disable-gprof --disable-gold --disable-gas
$ make
