Modified files:
lib/libc/stdlib malloc.c
Log:
Implement chunk allocation/deallocation hysteresis by caching one spare
chunk per arena, rather than immediately deallocating all unused chunks.
This fixes a potential performance issue when allocating/deallocating
an object of size (4kB..1MB] in a loop.
