Well, it's not, it's the reality of the situation and one I'd like to
protect against; "the scheduler must not die" is the rule I need to make
work...

The "Break" class, in reality, is the bowels of
twisted.protocols.ftp.FTPClient, copying from my previous mail:
self.failIfNotConnected(error.getConnectError((err, strerror(err))))
File "Twisted-8.2.0-py2.5-linux-x86_64.egg/twisted/internet/tcp.py",
line 588, in failIfNotConnected
del self.connector
--- <exception caught here> ---
File "ourcode.py", line 180, in checkSchedule
yield self.sendTransmissions(...)
exceptions.GeneratorExit:
How can I protect my scheduler against code which doesn't catch an
exception when it should?
cheers,
Chris
