Travis is failing :(

[pavel]

But why???
1257.1 Some timeout issues, when running in non-watch mode.
1257.2 Timeout when running "jade --help".

[pavel]

I ran npm run coveralls and it succeded. Well partially, in the end it failed, because it was not able to write report or smthn.

[ForbesLindesay]

I don't think we need to do this. When node exits it will just stop watching the files at that point.

[pavel]

Let me verify this.

I've added a few comments. Other than those, it looks pretty good.

To fix the timeouts, I would suggest going through https://github.com/jadejs/jade/blob/master/test/command-line.js and everywhere we have something like:

  if (isIstanbul) {
    this.timeout(8000);
    this.slow(6000);
  } else {
    this.slow(250);
  }

make it something like

  if (isIstanbul) {
    this.timeout(60000);
    this.slow(6000);
  } else {
    this.timeout(30000);
    this.slow(3000);
  }

We want timeouts that are way longer than we expect them to take, rather than having them on the brink of failing every time. Sorry for assuming your change caused this initially.

[pavel]

Sure, I'll increase the timeouts in this pull-request. Don't be sorry, you do what you gotta do.

[pavel]

I've left normalize, if anyone thinks that it's important to switch to resolve, then let me know.

@pavel I don't really like the test timeouts. 30 seconds is way too much for the timeouts, and 3 seconds for being slow isn't that reasonable either.

[pavel]

I did what @ForbesLindesay suggested. Not blaming, I'm not familiar with the test tools you use in jade, so I tend to listen to maintainers.
@TimothyGu What are your suggestions?

[TimothyGu]

@pavel how about this:

	istanbul	non-istanbul
TO	20s	12.5s
slow	3s	2s

[pavel]

Sure, let me update.

Cool. Merged, thanks!
