We may fail to submit a job because the SQE queue is full. Previously we would wait until some existing request completed, but that might never happen. Instead, we just flush the SQE queue and retry. Fixes ocaml-multicore#409.

The noop benchmark goes a bit faster with this, when you have more operations than queue slots:

CHANGES: New features: - Add `Eio.Net.run_server` (@bikallem @talex5 ocaml-multicore/eio#408). Runs an accept loop in one or more domains, with cancellation and graceful shutdown, and an optional maximum number of concurrent connections. - Add `Buf_read.BE` and `LE` parsers (@Cjen1 ocaml-multicore/eio#399). Parse numbers in various binary formats. - Add `Eio.Buf_read.uint8` (@talex5 ocaml-multicore/eio#418). Performance: - Make `Eio.Condition` lock-free (@talex5 ocaml-multicore/eio#397 ocaml-multicore/eio#381). In addition to being faster, this allows using conditions in signal handlers. - Make `Eio.Semaphore` lock-free (@talex5 @polytypic ocaml-multicore/eio#398). - Make `Eio.Stream` lock-free when the capacity is zero (@talex5 ocaml-multicore/eio#413 ocaml-multicore/eio#411). - Make `Eio.Promise` lock-free (@talex5 ocaml-multicore/eio#401). Bug fixes: - eio_linux: call `Uring.submit` as needed (@talex5 @bikallem ocaml-multicore/eio#428). Previously, we could fail to submit a job promptly because the SQE queue was full. - Fix luv signals (@haesbaert ocaml-multicore/eio#412). `libuv` automatically retries polling if it gets `EINTR`, without giving OCaml signal handlers a chance to run. - eio_luv: fix some resource leaks (@talex5 @patricoferris ocaml-multicore/eio#421). - eio_luv: fix "unavailable signal" error on Windows (@talex5 ocaml-multicore/eio#420, reported by @nojb). - Fix `Buf_write.BE.uint48` and `LE.uint48` (@adatario ocaml-multicore/eio#418). Documentation: - Add example programs (@talex5 ocaml-multicore/eio#389). - Update network examples to use `run_server` (@talex5 ocaml-multicore/eio#417). - Add a warning to the tutorial about `Fiber.first` (@talex5 ocaml-multicore/eio#394). - Clarify the epoch used for `Eio.Time.now` (@bikallem ocaml-multicore/eio#395). - Describe `secure_random` as an infinite source (@patricoferris ocaml-multicore/eio#426). - Update README for OCaml 5 release (@talex5 ocaml-multicore/eio#384 ocaml-multicore/eio#391 ocaml-multicore/eio#393). Other changes: - Delay setting `SIGPIPE` handler until the `run` function is called (@talex5 ocaml-multicore/eio#420). - Remove debug-level logging (@talex5 ocaml-multicore/eio#403). - eio-luv: improve `process.md` test (@smondet ocaml-multicore/eio#414). - Update to Dune 3 (@talex5 ocaml-multicore/eio#410). - Remove test dependency on Astring (@talex5 ocaml-multicore/eio#402 ocaml-multicore/eio#404). - Simplify cancellation logic (@talex5 ocaml-multicore/eio#396). - time: `Mtime.Spand.to_s` has been deprecated in mtime 2.0.0 (@bikallem ocaml-multicore/eio#385).
