This may cause next->io_len to reach 0 and trigger an assert at osmo_io.c:274: Assert failed next->io_len > 0 Add separate osmo_io_backpressure_test to verify queue management under network backpressure conditions. Use separate .ok files for poll vs io_uring backends since they produce different I/O patterns. This unit test reproduces the assert when the fix is not applied.
