I am not sure if scanning has stopped. epicsExit is hung up trying to
close the socket. The question is when that happens in the shutdown.
The epicsAtExit call to register that exit function is called when
the drvAsynIPPort is created, which is before iocInit. Does that mean
it will be called before or after record scanning is stopped?
epicsAtExit calls the handlers in inverse order. Last installed is first
called.
This probably does not answer the question. It depends on when in the
shutdown process the epicsAtExit handlers are called. I am not sure.
Probably via the C exit handler. That would be at the very end, i.e.
when exit() is called or main() returns. Also somewhere at that time the
C++ destructors are called. I don't know when this happens relative to
stopping the scan threads...
