I had ask a similar Q once and I've been told that (more or less):

It's because the clients of an allocator should rather statically 
check for specific traits of an allocator, there are too many 
possible permutations of capabilities possible, not all can 
allocate and deallocate, not all can reallocate, and so on.

actually I'm 100% sure that what you want is `isMallocator` and 
not `isAllocator` ;)
