Subject: [PATCH] fix: possible additional fix for non-terminating rrdtool
 processes. Sends the quit command to the process, but doesn't call close as
 that can block the php process. When the process exits all objects are
 destroyed and Proc::terminate() is called, this will terminate 15 then kill
 9.
