Description
If you have a large taxonomy (200 terms in my case), visiting /admin/build/menu/trails essentially crashes the browser (Safari). Oddly, Firefox loads the page a bit faster (I say odd because Webkit's "nitro" engine is faster at most js tasks), but it can still take minutes to render the page.

I've also experienced this in the past with the larger vocabularies. You end up getting prompted to terminate the script.
#2
A bit more information... even with javascript disabled, I noticed it takes about 15 seconds to load the page, and the HTML document is over 4 MB.
The crux of the issue seems to be that menutrails creates an option list for every taxonomy terms, containing all menu items. This means the number of options grows exponentially with the number of menu items and terms.
I have about 240 menu items and 300 terms, so that's 72,000
'#options'.
