Ah, the comment by Qarl Linden in the JIRA issue nails the issue for that
specific freeze bug:
"i'm not sure how our external svn is configured - but i can explain the
root of the problem. it's with our memory allocator (malloc/new/etc.) we
switched back at 1.21, and the behavior of the inventory system seemed to
trigger some kind of horrible worst-case scenario. with my demo above, i
switched to dmalloc. for the real fix in 1.23, we invoked some windows magic
to improve the allocator performance."

Might that help for this bug?
