OS Process Error: OS process timed out

There are 5 occurrences of the following in today's clam's couch log:

[Wed, 22 Jan 2014 16:24:14 GMT] [error] [<0.9208.0>] [982b25f4] OS Process Error <0.4435.0> :: {os_process_error,
                                                                "OS process timed out."}
[Wed, 22 Jan 2014 16:24:14 GMT] [info] [<0.114.0>] [--------] couch_proc_manager <0.4435.0> died normal

Some initial ideas:

• Currently, couch's @os_process_timeout@ is set to 5 seconds (the default).
• We have to check wether there are requests that will indeed take more than 5 seconds for couch to process (eg. large PUTs and GETs).
• We have to tune couch's @os_process_timeout@ configuration variable according to a good estimate of timeout.
