Subject: python2.3-qt3: QApplication.enter_loop seems to not release the GIL

Severity: normal
Using Twisted Matrix qtreactor (the Twisted Qt event loop wrapper) I noted that
when you call QApplication.enter_loop() python threads seems to stop, but that
doesn't happen if you use QApplication.exec_loop(). The enter_loop() method is
rarely used, but Twisted needs it. It seems that when you call enter_loop the
Python GIL isn't never released. Check this example:
#######
import threading, sys, time, qt
class SimpleThread(threading.Thread):
def run(self):
d = 0
while 1:
print d
if d == 15:
# to avoid killing it externally
sys.exit(1)
time.sleep(0.5)
d+=1
app = qt.QApplication([])
w = qt.QDialog()
app.setMainWidget(w)
w.show()
t = SimpleThread()
t.start()
time.sleep(2)
print "Executing QT Main Loop"
app.exec_loop()
#app.enter_loop()
#########
If you use exec_loop(), the SimpleThread continues to print the numbers
after the "Executing QT Main Loop Message", but if you use enter_loop,
the thread stops and no more numbers are printed after the previous
message.
