For this part: we recently added an experimental option to use direct
I/O (debug_io_direct). We are working on the infrastructure needed to
make it work efficiently before removing the "debug_" prefix:
prediction of future I/O through a "stream" abstraction which we have
some early pieces of already, I/O combining (see new io_combine_limit
setting), and asynchronous I/O (work in progress, basically I/O worker
processes or io_uring or other OS-specific APIs).
