This is to eliminate the possibility of having an in-flight async
contin access metadata that we destroyed in finalize().
This change is a bit pedantic, but since these vars aren't accessed
in any hotpath, it's fine to be pedantic. We made these sh_ptrs
atomic so we can use acquire and release side effects when loading
and storing them. This doesn't eliminate the problem of seeing
inconsistent state across microcontrollers, but it helps with simple
accesses like these ones we already do.
StagingBuffer:
We now allocate memory with mmap(MAP_ANONYMOUS) so that we can be
sure it can be pinned with io_uring_register_buffers(). This
ensures that if DMA is possible, it should be usable.
IoUringAssemblyEngine:
We now register an eventfd with io_uring so that we can listen
for CQEs with boost::asio.
