Comment 44 for bug 44062

regarding performance: i loaded the list from comment 24 using the patch i
attached, an measured how long the code i added to check the domain took. I only
measured worst case, that is where the domain isn't in the list. It took about
100usec per cookie set. (order of magnitude only)
So if one page tries to set 100 cookies, loading it will take 10msec longer. Is
that acceptable?

For memory footprint, it will be a little bit of code plus the size of the list.
The list i loaded is 7kb. This can all be in one memory block, no need for
malloc overhead. So a total of less then 10kb of memory.
