Ok, this one is *very* late in the shutdown process... there is code to: 1243 // stabilize the component manager, etc. but it looks like all of this code is designed to lead up to a single JS_MaybeGC and that in mozilla it is very likely that this MaybeGC will be unreachable. I guess the questions are: do we care? can we do anything about it? should we do anything about it?

Comment on attachment 110755 [details] [diff] [review] use an old fassioned jscontext Why the useless begin and end request calls if the cx is bound to a thread? Use a smaller stack chunk size, although it shouldn't matter (nothing called from here should allocate an arena from cx->stackPool). /be

Comment on attachment 112751 [details] [diff] [review] address comments r=dbradley The brace positioning is inconsistent with the majority of the code, but the file does have both styles. (I just don't like this particular style ;-)

Comment on attachment 112751 [details] [diff] [review] address comments I think shaver wrote this file, so he used 'if (...) {' style, not 'if(...) followed by { on a new line by itself, underhanging the i in if' style. Anyway, sr=me. /be
