----------------------------------+------------------------
 When an NFS server goes down in the middle of a recording any of the
 backend's ThreadedFileWriters writing to that disk become permanently
 wedged and CPU usage shoots up to near 100%.

 Using aio_write() instead of write() should allow us to better handle this
 condition. We should at minimum not use 100% CPU, and ideally continue
 recording to other disks including with the currently blocked recorder.
