Doing that per Josh's request, since it's causing very frequent intermittent OOMs on the android builders.

Doing that per Josh's request, since it's causing very frequent intermittent OOMs on the android builders.

Wow, what could cause that? any ideas?

[MortimerGoro]

@jdm what's the best way to try a lot compilations with the android builders in a new PR? Is there any bors-servo command to test compilations only on android builders?

I never had that OOM in my local rust compilations. I can try to remove a template parameter from the WebGL thread or the webrender dependency in canvas (just needs a small change in WR). It's the only reasons which I think could cause that kind compilation of error. The other code is normal.

[jdm]

@MortimerGoro It's probably most useful to add your ssh key to https://github.com/servo/saltfs/tree/master/admin/files/ssh and try building directly on the android builder.

@edunham Can we upgrade all the linux cross builders to something with > 8GB of RAM (at least 16 GB)?

[jdm]

We continue to have memory errors after reverting this PR; my apologies for assigning the blame incorrectly. You are welcome to re-merge these changes.

[MortimerGoro]

@jdm no problem, I created a new PR to re-merge the WebGL redesign ;) #18119

[MortimerGoro]

Closed the new PR, I didn't see that @nox had already created it
