the section about memory allocators severely underrepresents state of art of systems memory management. 

current memory allocator of choice in many places is 'jemalloc', and some other suggested 'leading memory allocators' are neither leading nor useful for MySQL (e.g. allocate memory in powers-of-2, etc)

How to repeat:
read the manual

Suggested fix:
revisit the section, point out 'jemalloc' as a primary candidate for high performance memory management
