test failures on Linux

[happybeing]

I've been seeing these for a while (doing regular builds and tests of everything using nightly Rust) and reporting them in case. Is this expected, or due to my not having something set up here?

Thanks for reporting the issue.
Currently crust tests don't support parallel run.
As rust runs tests in parallel by default, we need to set the variable: RUST_TEST_THREADS.

Set this variable and you should be okay.
export RUST_TEST_THREADS=1
