* Fix the directory service usage by saving the pending directory path from OOPInit. * Force clients to call OOPInit on the main thread. * Make injected crashes available via TakeMinidumpForChild and give each crash a sequence number so that we can pick the earliest crash from the three possibilities; delete the other two to avoid polluting about:crashes
