For purposes of locality in the minidump file, I’d like to keep the thread
stacks contiguous in the minidump file. So this ExtraMemory() add should be in a
separate loop that runs after all of the AddThread() calls are done.

I’ve got this idea that a future minidump reader might be able to make some
sense out of incomplete files, so I’d like the more important stuff like thread
stack memory to ride up front, and the less important stuff like miscellaneous
memory regions to follow.

Done.
