As can be seen from the pid numbers provided, first ps/top output 
in my previous message is from the initial nginx start, and the 
reload shown is the first one.

What looks like an important factor is "junk:true" in my 
malloc.conf.  Without at least "junk:free" I indeed see similar 
results to yours - most likely because kernel fails to free pages 
which are referenced from multiple processes when madvise() is 
called.
