macOS 后台 PyQt 线程执行超时

Question

当我在后台点击最小化按钮执行这个操作时，线程经常执行超出限制的时间，后台唤醒程序恢复正常。请耐心等待，大约一分钟后就会出现。

import sys, random, time, functools
from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QMainWindow, QHBoxLayout
from PyQt5.QtCore import QThread, QObject

def clock(func):
    @functools.wraps(func)
    def clocked(*args, **kwargs):
        t0 = time.time()
        result = func(*args, **kwargs)
        elapsed = time.time() - t0
        name = func.__name__
        l_arg = []
        if args:
            l_arg.append(', '.join(repr(arg) for arg in args))
        arg_str = ', '.join(l_arg)
        print('[%0.5fs] %s(%s)' % (elapsed, name, arg_str))
        return result
    return clocked

@clock
def go_sleep(sleep_time):
    time.sleep(sleep_time)

def go_run():
    for i in range(100):
        go_sleep(random.randint(1, 3))

class WorkThread(QObject):
    def __int__(self):
        super(WorkThread, self).__init__()

    def run(self):
        go_run()

class WinForm(QMainWindow):
    def __init__(self, parent=None):
        super(WinForm, self).__init__(parent)
        self.button1 = QPushButton('Run')
        self.button1.clicked.connect(self.onButtonClick)
        self._thread = QThread(self)
        self.wt = WorkThread()
        self.wt.moveToThread(self._thread)
        layout = QHBoxLayout()
        layout.addWidget(self.button1)
        main_frame = QWidget()
        main_frame.setLayout(layout)
        self.setCentralWidget(main_frame)

    def onButtonClick(self):
        self.button1.setText('Running')
        self._thread.started.connect(self.wt.run)
        self._thread.start()

if __name__ == "__main__":
    app = QApplication(sys.argv)
    form = WinForm()
    form.show()
    sys.exit(app.exec_())
