[diegorusso]

The old machine has been decommisioned and replaced with a new more powerful one.
This is an AmpereOne with 192 cores and 500GB of memory.

LGTM

192 cores

That's a few cores;-)

I moved under unstable because of the folloiwng issues:

• test_urllib2net will fail as the outbound ftp connection is blocked for now. I've requested to unblock it.
• test_embed is sensitive to the virtual environment where buildbot is installed. I've run it now without activating it but calling directly.
• test_bigmem used to timeout but it should be OK now.

Merged. Let's see how it goes.

A first build has completed, sadly it failed: https://buildbot.python.org/#/builders/1832/builds/1 FTP tests of test_urllib2net failed with TimeoutError/URLError.

Diego is aware of the issue:

I've already informed the IT department to unblock the ftp connection. I'll keep you posted. This is why I put the worken in the unstable section for now.

The _decimal C extension is not built. You might try this recipe to install its dependency libmpdec:

Done, I've added to my notes!
