The Intermittent Stability Issues That Nobody Can Pin Down

[Wowfunhappy]

I feel like #94, #44, #67, #75, and #80 are all basically related, stemming from general instabilities which exist within Chromium Legacy. Chromium does a pretty good job of hiding problems by silently restarting the affected subsystem, but sometimes we see side effects like a page going blank or a browser extension crashing.

For example, if you launch Chromium via the Terminal, you can see when the network process crashes and is restarted. These crashes frequently (but not always!) accompany instances of the aforementioned issues.

This was why I thought the best realistic fix for #75 was to simply auto restart extensions as well. Because I think what (sometimes) happens is:

1. A network process crashes.
2. UBlock Origin (for example) was is in the middle of filtering some network request when the process crashed. UBlock Origin quite reasonably cannot handle this case, and so it crashes as well.
3. The network process is silently restart, but UBlock Origin is not.

To be clear, I don't think the network process specifically is always at fault.

I don't really know how to even begin investigating the root causes of these intermittent problems, particularly as rebuilding Chromium from source is so challenging. One possible lead is that these problems all seem to occur less frequently on a fresh profile.
