Log Message:
-----------
hp malloc: fix shm statistics
* processes now update fragment statistics for each bucket
* the MI workers iterate and aggregate all memory information
* the built-in maximum sampling rate is 200ms
- repeating a fetch in < 200ms will return the same results
* this patch also corrects a rare deadlock in hp_realloc
- hp_realloc "growth" may deadlock with hp_malloc "shrink"
- the best solution is to drop the "growth" realloc operation
- this also merges well with the allocator fragmentation
