[Buildbot-devel] What will happen if I do reconfig when BuildSlaves are building ? Is it predictable ?

[fish47]

 Hi everyone. I'm a Buildbot newbie. Recently I came across a problem as you can see from the title above. It seems that there's no document of this topic available.
What will happen if I do reconfig while the BuildMaster is busy or the BuildSlaves are building ?  Although "buildbot.master.BuildMaster" instance will invoke ".loadTheConfigFile(self, configFile=None)" as soon as possible. But will everything (Schedulers, Builders, BuildSteps of each Builders, and so on) keep synchronized and valid after that method finished ?
Thank you for your time.
