Concurrent Disk IO in Object Server
Registered by
Samuel Merritt
Eventlet doesn't help with file IO; the whole process still blocks. Use external real (i.e., not green) threads to allow for actual concurrent reads on multiple disks. That's sufficiently cross-platform that it shouldn't tick off the Illumos / FreeBSD folks too badly.
Extra bonus points for ensuring that a single slow disk won't end up with all the threads stuck waiting for it.
