As apposed to other versions, the @code{malloc} in GNU libc does not

round up block sizes to powers of two, neither for large nor for small

sizes. Neighboring chunks can be coalesced on a @code{free} no matter

Very large blocks (much larger than a page) are allocated with

@code{mmap} (anonymous or via @code{/dev/zero}) by this implementation.

This has the great advantage that these chunks are returned to the

system immediately when they are freed. Therefore, it cannot happen

that will cause @code{sbrk} to be called with a negative argument in

||||
order to return memory to the system.
|
||||
@item M_TOP_PAD
|
||||
This parameter determines the amount of extra memory to obtain from the

system when a call to @code{sbrk} is required. It also specifies the

number of bytes to retain when shrinking the heap by calling @code{sbrk}

All chunks larger than this value are allocated outside the normal
