I am using Wine to run Poisson Superfish. This program essentially does some
calculations and then writes the results into a binary file. This action is
performed in less than a second in a Windows environment. Unfortunately, it
takes about 10 seconds to write this binary file under Wine. Here is how to
reproduce the error:

1. Install Poisson Superfish on linux using Wine. You have to scroll all the
way down and click register.

2. Once installed, open a unix terminal in this directory
.../.wine/drive_c/LANL/Examples/RadioFrequency/Waveguides/
3. Run wineconsole cmd.
4. In the new window, run RUNWG.BAT.
3. Several windows will pop up. The ones that stall for a bit are in the
process of writing to a file named something.T35. The T35 refers to tape 35 (I
guess that's how a sector of harddrive memory would be referred as back in the
80s). This is the binary file with the solution in it.
It will finish eventually, but it is pretty slow.
