[swfmill] stdin & stdout

[Dan Shryock]

I haven't tried the asynchronous calls because the output is binary
data (should be the same for you because the output is a swf file).
Instead I've been using the process.StandardOutput.BaseStream to read
the data, and there are only blocking read methods there.  I think
this is thread safe, but I may be wrong (and that may be why I can't
ever get reliable results).  I've searched for examples of how to
handle this type of situation, but I haven't found anything good.
