As I said - heap management is usually mostly done in userspace.  The way the
standard glibc malloc() call does things is almost certainly different from the
way other C libraries such as uClibc or klibc or dietlibc do it.  Then there's
a number of debugging malloc() packages, and so on.

The only way the kernel gets involved is when the userspace malloc() library
decides to call brk(), sbrk(), or mmap().
