Is this intermittent, or a constant failure on 18.04?

It has been failing for multiple builds - https://ci.swift.org/job/oss-swift-incremental-RA-linux-ubuntu-18_04/

Thank you. Has this test ever passed on 18.04? Sorry, I find Jenkins extremely difficult to navigate and understand.

Looks like it passed once before

OK, thank you. I think we should probably comment this test out for now, pending an investigation. Is that ok?

@parkera, Are you ok with ianpartridge (JIRA User) suggestion?

Can we disable it only for Ubuntu 18.04?

Otherwise, my usual objection applies. Disabling the test just hides the failure, which means we ship a known bug.

@parkera Not sure if lit has a support for disabling test for specific OS version.

If we need to unblock things here, we can comment out the test and use this bug to track it.

This was fixed, along with some other `TestURLSession` issues that had been exposed on Ubuntu 18.04, in #1602
