SIGKILL (OOM?) for documenting web-sys 0.3.46

[alexcrichton]

Crate name: web-sys
Build failure link: https://docs.rs/crate/web-sys/0.3.46/builds/321002

Additional details:

Is it possible to figure out why SIGKILL was received on this build? I think that OOM is the obvious suspect since this is a huge crate with all of its documentation enabled (which we do for docs-rs). I wanted to ideally confirm though that this was OOM-killed before trying to do something else.

Otherwise, if the memory limit can't be raised, I suspect the next step is to open a bug on rustdoc itself!

Not without running cargo doc or a local docs.rs instance, unfortunately - I'd love to have it though: #878.

I can definitely raise the memory limit in the meantime, it will probably be a while before rustdoc's memory consumption improves (although if the cause is different here than in rust-lang/rust#79103 I'd love to hear about it 🙂)

$  command time -v cargo doc --all-features
	Maximum resident set size (kbytes): 3117768

Yup, this just hit the limit. I'll bump it to 5 GB for now, that should be enough for a while.
