Discussion:
After 6 minutes or so of using 50% my 4-core MBP CPU and chewing up a ton of memory, make release gives up with a timeout.
This is on my master branch (no local changes) after rebasing to head this evening. It was working fine earlier today so seems like the likely culprit. /cc
It's certainly my changes. I'm on a low function device, feel free to revert. This is only an issue for low memory systems, I suspect. :/ On Apr 1, 2015 10:24 PM, "Robert Bailey" wrote:
