I have marked all Web inspector related tests as slow in r257051 for Debug. I was going to mark them as timing out, but I decided to give them a run locally to check if in slow they passed and most of them did. I just marked as timing out the ones that timed out locally. Will check on the Debug bot after the next run if there are more timing outs and if needed mark them as timing out if this continues to be an issue.

Ok, the debug bot has stopped exiting early due to this unexpected timeouts, and we now most of the inspector tests are completing the run in debug, just marked as slow so the testrunner gives them extra time to run. There are still some issues with the Web inspector tests there on the last run. Many giving text failure, one timeout and one crash. https://build.webkit.org/builders/GTK%20Linux%2064-bit%20Debug%20%28Tests%29/builds/5941

Created attachment 421864 [details] WIP patch WI.dispatchNextQueuedMessageFromBackend is using setTimeout, but it is very slow because it is throttled by 1 second.

This is a bug ticket for Mac. Bug 147456 – LayoutTests/inspector frequently run slow and timeout when run in WebKit2 but not WebKit1

Looks like the Windows client is also missing this switch. Any way we could make this more cross platform?
