Just a thought, but since a directory tree is a first class item in cephfs,
could the wire protocol be extended with an “recursive delete” operation,
specifically for cases like this?

Ah yeah, if you're in whatever they call the recursive tree delete
function you can unroll that loop a whole bunch. I forget where the
boundary is so you may need to go play with the JNI code; not sure.
