-Subject: [PATCH] ocaml: Release runtime lock around call to nbd_close
-
-OCaml 5 is stricter than earlier versions about correct locking.
-
-We must release the OCaml runtime lock when calling nbd_close since it
-may do some long-running operations and we want to allow concurrent
-threads to run.
-
-However specifically if there are callbacks (eg. a debug callback)
-then we would end up trying to re-acquire the lock in the callback,
-resulting in a crash:
