This is timing out after completing the last test in this file. Quite likely for the same reason we added this lovely workaround to this test: https://searchfox.org/mozilla-central/source/layout/style/test/test_parse_rule.html#252 What if we knock that down to 0. Jan: WDYT?

Sure, worth a try, although I guess that the gain from that won't be nearly as dramatic as the original one when going from the default 50 down to 4.

In the last 7 days we have 30 failures. They occur on android-4-3-armv7-api16 and the affected builds type are debug and opt.

Apart from the quick fix of cutting down on any remaining session history overhead or simply requesting a longer timeout, this actually means that we've had some performance regression in that area. While the time taken to complete the test had been borderline for some time already, the failure rate started really picking up in the week ending 2017-11-27 02:18 CET, which coincidentally was the week that Stylo was enabled by default on Android (bug 1366049).

That sounds... plausible. Stylo is known to be slower on ARM, see bug 1430706.

Debug build of Stylo's CSS parser is extreme slow due to no LTO. Even if opt build, no-LTO is 2x-3x slower than LTO on Android's real device.

This has an abrupt spike in failure rate after this merge: https://treeherder.mozilla.org/#/jobs?repo=mozilla-inbound&searchStr=android%2C4.3%2Capi16%2B%2Cdebug%2Cmochitests%2Ctest-android-em-4.3-arm7-api-16%2Fdebug-mochitest-57%2Cm%2857%29&selectedJob=230043476
maybe from Bug 1529607? kato, could you take a look over it? thank you.

This failure issue is that Android/arm build runs on emulator, and CSS parser of Stylo is a little slow than original C++ parser.

If we can change timeout value to a little long, this doesn't occur. Stylo's CSS parser is fast on x86 device, but arm is a little slow.

Based on comment 72 it sounds like the test was flaky and relying on timing so the test should be fixed by a relevant peer.

We should use requestLongerTimeout.

Although debug build of Android/arm runs on emulator, test_parse_rule.html
sometimes run over 5 min. So we should extend timeout value for this.
