Error running tests about delve HOT 5 CLOSED

Yeah, it seems to be a flickering failure but it's definitely there. I'll look into it, I may have an idea why this is happening.

from delve.

So, for some reason on my laptop (Debian Jessie running kernel 3.17) the tests pass fine 99% of the time, with occasional, but rare flickers. However, on an Ubuntu 14.10 vm I have the tests always seem to fail consistently on master.

I'm going to investigate this more and try and figure out what is causing master to fail on certain machines, and under what circumstances.

from delve.

It seems to always fail on both VMs for me (Ubuntu 14.04 and CoreOS 561)

from delve.

So, on the ubuntu VM that reproducibly fails, I have TestNext and TestVariableFunctionScoping failing consistently. I have tracked down why TestNext is failing, it's due to m.procid not being set correctly for a newly created thread. No idea why this is happening, I'm running go 1.4.1 on both my actual machine and on the VM and the VM fails whereas on my machine all tests pass with no problem.

Haven't dug into the TestVariableFunctionScoping failure yet, but it could be related.

I just tried on GCE on Operating System: CoreOS 575.0.0

@epipho what are you using as a host VM?
