Modified files:
lib/libc/stdlib malloc.c
Log:
Optimize realloc() to reallocate in place if the old and new sizes are
close enough to each other that reallocation would allocate a new region
of the same size. This improves the performance of repeated incremental
reallocations by up to three orders of magnitude. [1]
Fix arena_new() to properly constrain run size if a small chunk size was
specified during runtime configuration.
