Proposition: I have made a small proposed patch to newcron.py, in order to keep a list of cron subprocesses and send a terminate signal when web2py exists. See attached newcron.py.diff. A lock should be added when accessing the _cron_subprocs list, to avoid thread concurrency.
Also, I noticed that newcron.stopcron() is called when closing the widget window if the web server was started. But if the web server was not started, it will not be called, which is strange, as cron is started before the web server. The second attached patch (widget.py.diff) fixes this to call newcron.stopcron() on exit. I guess same fix should be applied for winservice.py, and similar for the --nogui case. What do you think about this proposed changes? Thanks.
