Thanks for your answer !
I will definitely look into these allocators to see if I can get
`serialization_buffer<>` to work with memory which has been pinned both
for the network and for the CUDA runtime.
However I fear I don't have enough knowledge yet to start hacking on
the HPX internals.
Best regards,Jean-Loup
