VIRT memory on Linux at >80GB+.

[duckinator]

Testcase, using web-view v0.4.0.

extern crate web_view;

fn main() {
    web_view::builder()
        .content(web_view::Content::Html(":("))
        .user_data(())
        .invoke_handler(|_w, _a| Ok(()))
        .run()
        .unwrap();
}

I updated the title because, while discussing it elsewhere, I was reminded that VIRT refers to the entire virtual memory address space. This means it includes mmap() and MMIO and friends, not just malloc() and friends.

So, not inherently as bad as I thought, but it still very much seems like a bug.

I'm not sure when I'll get to it, but my current plan re narrowing down the cause is roughly:

1. Attempt to reproduce using zserge/webview from C, C++, and Go.
2. Attempt to reproduce by using gtk-webkit directly.
3. Depending on which of the above (if any) could be used to reproduce it, attempt to narrow down the root cause.

Reproduced the problem in C.

I'm going to close this issue, since I reproduced it using only C and webkit2gtk+: https://gist.github.com/duckinator/4c8a2fd8b898c6aa1e4a44d9c61b4d57

Sorry for the noise while narrowing it down!
