./mach clean-nightlies fails on servo-mac5

[pyfisch]

This happens at PR #20420 for no obvious reason. Any suggestions?

See:

• http://build.servo.org/builders/mac-rel-wpt3/builds/4246
• http://build.servo.org/builders/mac-dev-unit/builds/11755

Yeah, it's known, has happened in a bunch of other PRs. We're trying to address it ATM.

I'm currently landing d52011c to just not use clean-nightlies right now.

I tried to remove servo-mac5 from the build machines pool but couldn't do it from the Web interface.

Can I try to build #20420 again? Should I rebase the PR?

[nox]

I retried it, thanks for telling me about it, I didn't notice it was stuck because of this issue.

[nox]

If there are no conflicts you shouldn't need to rebase, FYI, because our CI stuff tries PRs with a merge of master.

Don't think this is relevant any more.
