This issue is similar to bug 167622 and 167637 and happens with the test IndexedDB/objectstore-cursor.html * On the GTK+ perf bot sometimes deadlocks and timeouts, and sometimes works. * When it works it finish in 3-4 minutes. * By looking at the top output you know when it has deadlocked, because when it works both the Web and DataBase process keep using the CPU all the time, but when it deadlocks both process stall and not longer use more CPU time. * The backtraces from the GTK+ perf bot are similar to the ones for IndexedDB/index-get.html from bug 167622 and 167637.
