Once all applications are switched to using the new initialization code, we can get rid of XRE_WANT_DLL_BLOCKLIST, which was kept for compatibility. Patch against current m-c is https://bugzilla.mozilla.org/attachment.cgi?id=522983, but it is likely to bitrot with bug 658847.
Do you happen to recall which bug/patch-set did the "new initialization code" ? So we can get bugs open on Suite/TB and mark proper bug dependancies.
