Created attachment 8497349 [details] profile_captured_highcpu_1.sym Observed by profiling B2G process on a Nexus S, on a build from sept. 25th. Profile: http://people.mozilla.org/~bgirard/cleopatra/#report=9f32e34cd7c2628d1f7e26a9bf8bc3a0c6fa06a5 Restyles is triggered by aw_destroy()
Etienne, maybe you can help me to have a look?
When we destroy an app (oom-kill or user-kill) we remove the dead iframe from the DOM so we're going to reflow anyway. Was the flush particularly long? Not sure there's a bug here.
Well I noticed the Restyles call, but it's your call to consider whether there's a bug or not according to the profiling I provided :)
