...help. Assumption: (i) "pid" is set to unicorn.pid in the config file; (ii) a Unicorn process is already running. (1) kill -USR2 `cat unicorn.pid` (via Capistrano deployment task for example) (2) Inside the "before_exec" hook in the config file, do: kill -QUIT `cat unicorn.pid.oldbin` My question is: By the time the "before_exec" hook is executed, is it guaranteed that unicorn.pid.oldbin ahas lready created (otherwise we have a racing condition here)? Or is there a better way to achieve what I want? Please Cc me as I am not on the mailing list. Please also let me k...

How could I get unicorn to rename the pid file back to unicorn.pid ? I see some code in method +reap_all_workers+ that suggests it wou...
