Two things were suboptimal from a performance point of view:
a) consider a large media object such as a video keyframe, which
may be split up into multiple fragments. We would assemble
the media object as follows:
buf = join (join (join (frag1, frag2), frag3), frag4)
which causes many unnecessary memcpy()s, and malloc/free,
which could easily add up to a multiple of the actual object
size. To avoid this, we allocate a buffer of the size needed
from the start and copy fragments into that directly.
b) for every fragment to join, we would create a sub-buffer
before joining it (which would discard the sub-buffer again),
leading to unnecessary miniobject create/free churn.
