Allocators should not work without an internal state. The fact
that the heap chunk you get is mallocated or gcallocated
shouldn't be a concern. The data structure can still use internal
policies about how to request memory.
At the same time with allocators it's another problem. I'd say
that the old-fashioned strategies shouldn't slow down the
growing, even if the memory provider is better.
I don't know if you understand what i mean but in short:
Appender!(SpecializedAllocator, int[])
shouldn't be slowest than
Appender!(int[])
despite of the internal tweak that already exist. With allocators
the situation is a bit confuse: who does provide the improvement ?
