I'm not 100% sure it wasn't caught by the spam filter on the way out :) So I'm reposting this - as I never got any more responses.
Please see my latest post below - Thanks!

While that does illustrate how convoluted the process becomes when you have so many layers (as in this case), it seems to me that it's the point where there is no free memory left to allocate that ruins the party. I may be missing something here - please correct me if I'm wrong. If the problem only manifests when the system is under memory pressure, is it not possible to avoid the deadlock if you manage your memory very strictly? To extend that even further, it might it also then be possible to quantify how much spare memory you need to have in reserve to guarantee operation without a deadlock? Are their factors to consider other than memory that might cause the deadlock?
