Just follow inc_num and you will understand. Now _resize will grow the list to match
the required number of elements as described in the comment in the .h file.

constrained:
* Make sure we always have a number of eager fragments available
that scales with the number of processes communicating with
a given proc over shared memory
* Use FREE_LIST_GET instead of FREE_LIST_WAIT to return an
error to the PML when resource exhaustion occurs
* Don't dereference the frag during alloc unless we're sure
it's not NULL

was smaller than the CACHE_LINE_SIZE. Here is the version that works.
In fact this works on 2 steps. First we set the element size to something
multiple of the desired alignment. Then when we allocate memory, we compute
the total size, and we will align each of the elements (we allocate
multiple of them every time) to the CACHE_LINE_SIZE.

bytes). The simplest way to make sure they are aligned is to update
the size of the basic element to a multiple of the desired alignment.
It will use a little bit more memory, but the improvements on the SM BTL
seems quite interesting.

free list. It use the size attached to the free list, and the internal
memory segments to find out all the items allocated by this free list.

The free lst using atomic operations. I didn't want to completely
change the behavior, so we still use a mutex for the extreme cases (like
no more available items and we cannot allocate more). I test it for a
while on non multi-threading environment, but not enough on a multi-threaded
build.
