Thanks for the fix, @isabelleh!

Oh no, testParallelPerformance failed @adahn6. Might be worth looking into it.

@MikeGost oh no >.< alright, I think it's probably best to just comment out that test then? It's still somewhat useful as a performance check, but clearly not reliable enough to be included by default

[MikeGost]

@adahn6 - Let’s add the @ignore annotation for now and create an issue to replace it with something better or remove altogether.

I too have been bitten by my own questionable multithreaded tests :)

Thanks for the fix, @isabelleh!

@isabelleh - Do you mind adding the @Ignore tag to the failing test in this PR - that way we can merge it and remove the chance of a failing build in Travis. Meanwhile, I'll create an issue to address this.

Relevant issue: #250

Requesting changes to add Ignore tag.
