 I don't know whether it's related to the new code to "hold" a page to a
 circuit, or that being announced made me glance that way for an
 explanation, but the 4.5 release is "pick a euphemism for the opposite of
 successful" in building a new page, on certain sites, with a single
 circuit - sites that the 4.0.8 release handles just fine.

 Two examples are nitroflare.com and uploadable.ch. They're both scripted
 ad and captcha infested steaming piles o' joy - that try to do the "IP
 address is a person" voodoo. So, when TBB 4.5 opens at least three
 circuits, commonly using three exit nodes, just to render the landing page
 - even if the scripts and captchas are successfully navigated through, the
 odds of the final click coming from what the server "thinks" is the valid
 address is less than 50/50. TBB 4.0.8 allows you to inflict that suffering
 on yourself with a single circuit - which, of course, uses a single exit
 node. And, it does so consistently. TBB 4.5, from what I've been able to
 test, is also consistent - but that's not a good thing.
