[mod_python] This is just friggin' weird...

Okay, and something else I've discovered... it appears to be hanging on 

Now, at least in my experience, psp.redirect will throw an error if 
data has been written back out to the client when redirect() is called. 
It's not doing that. It's just... hanging.

The way I discovered this was by accident. I was testing it by 
telnetting to port 80 and manually entering for data. I accidentally 
left off a field, and it hung at a different place it had ever hung 
before. At that spot, there's a psp.redirect to an error handler...

So... why? I don't get it.
