This is blocking the CI so I'm going to disable it temporarily.

This failure isn't consistent. It fails and passes randomly, here's another one:

This is a super old bug but it was in the alpha4 milestone, so moving to RC1 to reevaluate.

[muratg]

Just talked to @lodejard. Moving is issues to RC2.

[lodejard]

Reassigning to @halter73 for investigation or closing if needed

[halter73]

I've been running these tests a lot the last couple days on various platforms, and I haven't seen this issue. In fact, I haven't seen any of the EngineTests fail with an Assert.Equal failure or an IOException in well over a month.

The EngineTests hanging on Mono are another story of course...

[muratg]

We'll reactivate if this is still an issue.

[halter73]

@muratg Do you want me to continue investigating this? Should I remove the Done label?

[muratg]

I had an exception a couple days ago but later passed fine, though I'm not sure if it works fine now or not. Keeping open for now.
