I understand those are your needs, but there are multiple other people who've requested this specifically in order to get web services or node-side services into the picture.  I don't think we can call #5137 fixed if we're timing after just 1 sec.  How about we just raise it to 5 or 10 sec for now?

It also seems weird that this is a single global pref rather than an option linters can specify when registering, or a per-linter pref.  I think we'll need to revisit that if there are complaints about the default timeout, but for now it seems ok (as long as we bump up the default here).
