不调用Thread#join可以吗？
不调用Thread#join可以吗？在这种情况下，我不在乎线程是否崩溃 - 我只希望 Unicorn 继续处理。
class MyMiddleware
def initialize(app)
@app = app
end
def call(env)
t = Thread.new { sleep 1 }
t.join # is it ok if I skip this?
@app.call env
end
end
我会得到“僵尸线程”或类似的东西吗？
Is it OK not to call Thread#join? In this case, I don't care if the thread blows up - I just want Unicorn to keep processing.
class MyMiddleware
def initialize(app)
@app = app
end
def call(env)
t = Thread.new { sleep 1 }
t.join # is it ok if I skip this?
@app.call env
end
end
Will I get "zombie threads" or something like that?

不调用
join是完全可以的 - 事实上，多线程代码通常根本不需要join。仅当您需要阻塞直到新线程完成时，才应调用join。你不会得到“僵尸”线程。新线程将运行直到完成，然后为您清理自身。
It's perfectly fine to not call
join- in fact,joinis often not needed at all with multithreaded code. You should only calljoinif you need to block until the new thread completes.You won't get a "zombie" thread. The new thread will run until completion, then clean itself up for you.
