Does Gunicorn suffer from the thundering herd problem?
------------------------------------------------------
The thundering herd problem occurs when many sleeping request handlers, which
may be either threads or processes, wake up at the same time to handle an new
request. Since only one handler will receive the request, the others will have
been awakened for no reaon, wasting CPU cycles. At this time, Gunicorn does not
implement any IPC solution for coordinating between worker processes. You may
experience high load due to this problem when using many workers or threads.
