1215847 - triple WinUtils::WaitForMessage hang with three processes

Status: RESOLVED DUPLICATE of bug 1213671

(Core :: DOM: Content Processes, defect)

Description

[Jim Mathies [:jimm]]

While surfing the web today, hit this when I tried to open dev tools using ctrl-shift-i. 

Interestingly chrome was still responsive, I was able to right-click and bring up context menus and such, and i was able to resize the window. However painting was frozen, and content was unresponsive to user input.

It shouldn't be hard to detect something like this and break out of it.

This appears to be reproducible, STR:

1) make sure apz and e10s are enabled.
2) visit http://www.sudholtsheetmetal.com/shower-drains.html
3) scroll down and click on one of the 'View Larger Image' links underneath one of the custom drain cover images

result: hang

Forgot the last step:

1) make sure apz and e10s are enabled.
2) visit http://www.sudholtsheetmetal.com/shower-drains.html
3) scroll down and click on one of the 'View Larger Image' links underneath one of the custom drain cover images
4) type ctrl-shift-i

You also need flash installed and activated.
