Note also that something (not sure what) has made fragmentation

Actually it seems to be situations like the stack now being two pages
Instrumentation posted here before appears to corellate fragmentation
being /caused/ with I/O activity (single bonnie process and thus a
single 8k stack frame). My own guess is that it is due to
a different persistence of various caches.
I haven't seen anyone before blaming stack frame allocation
as a /cause/ of fragmenation - I've heard people say they
notice fragmentation more as stack frame allocs start to
fail - but that's a symptom.
