Cache miss stampedes

[Brad Fitzpatrick]

This is totally the wrong list, but...

Gearman:  low latency, failures/retries done by client (who's waiting,
perhaps on dozens of things in parallel).  No disks involved.  Just load
balancing function calls inside your network.

TheSchwartz:  high latency.  retries done by system.  database(s)
involved, thus disks.  use for long/slow tasks like sending email or SMS
or video transcoding, etc... gearman is for calling functions elsewhere on
your network while you wait.

Both complement each other wonderfully.  Neither is going away nor being
folded into the other.
