No, they're most likely waiting for io to complete.

To clean this up I've got a patch to move from aio_read/write with all the
parameters to a single parameter based rw-specific iocb. That makes the
retry for read and write more ameniable to sharing common logic akin to the
wtd_ ops, which we need at the very least for the semaphore operations.
