should wait until after?
I'm about to post a series adding a .cleanup callback (counterpart to
.after_fork, and called in outer-to-inner order, opposite of .unload
called in inner-to-outer order), in order to modify the ext2 filter to
allow multiplexed connections.

For me, but none of them are urgent before this release:
Proposed nbdkit-forward-filter which ensures that we only do forward
reads over the plugin.
nbdkit-readahead-filter fix/replacement. Requires background threads,
this may be possible already.
Not easy without a .cleanup callback (it IS possible to create a
background thread, but .unload is too late to clean that thread up
gracefully to ensure we close the plugin's handle without accidentally
calling into unloaded memory).
