rust dies reliably during a firefox build with --jobs=1 with: thread 'main' panicked at 'failed printing to stdout: Resource temporarily unavailable (os error 11)'

quote from the build.log - this all seems to be warnings:

[stefson]

it used to work back in February:

 Sat Feb 23 11:13:47 2019 >>> www-client/firefox-65.0.1-r1
   merge time: 1 day, 1 hour, 39 minutes and 32 seconds.

with I believe rust-1.30.1

[Pistos]

I cannot build Firefox 67 either. Here is my build log: https://bpaste.net/show/1e2192eaa3c2

[stefson]

I saw that you did pass -j1 to the build process, could you try to use something else, -j2 mabye? I can't, as the arm machine has only 1gig of ram and thus isn't going to handle it memory wise.

[Pistos]

@stefson You're right. I changed it to -s -j2 -l 3, and the build finished. Thanks. Why would this make a difference, though? And what made you suspect that as the problem?

[stefson]

any ideas on how to debug this further?

[bsdkurt]

This is a duplicate bug of #57632. Root cause was non-blocking stdout set by node in earlier in the firefox build. cargo is not prepared to deal with non-blocking stdout. See linked bug report for further details.

[stefson]

You're right, thank you! I can now confirm that this happens due to https://bugzilla.mozilla.org/show_bug.cgi?id=1500436, which is actually a bug in the node.js stuff -.-
