[Wine] Wine + serial port basically hangs system

[Dan Armbrust]

Ok, thanks for the tip on 'lsof' - I alway forget that command.  Sorry
about going off list, I hit the wrong link.  Still getting used to the
gmail interface.

After I did some hunting with lsof, I discovered that X was using
ttyS0, even though it shouldn't have been.  So I commented out the
necessary parts of the config to stop that.  Then, I discovered gpm
was also using the serial port.  Killed that.

Restarted the machine, ran my app, and boom - it connects up, and pulls in data.

Now, I'm back on-topic for this thread - the machine load still
spirals out of control when it runs.

Here is the last capture from top that I was able to get (this is
after the program had been running for a couple of minutes)

top - 18:28:57 up 12 min,  2 users,  load average: 27.42, 14.38, 6.40
Tasks:  98 total,  14 running,  84 sleeping,   0 stopped,   0 zombie

And here is the output that I got from the launch of the app:

 wine heavy\ weather.exe

The app continued to pull in data intermittently, even as the machine
entered a death spiral - but I couldn't do anything else - even though
top was set to update ever second, it was only coming in with new
numbers about once a minute.  As soon as I kill the weather app,
everything returns to normal.

Thanks,

Dan
