File uploads and client_body_temp_temp problems

I find it hard to believe that, with all these sites working behind  
nginx that there isn't a better answer than "Switch web servers".   
There must be someone here doing file uploads, since it is a very  
common webapp requirement.

Is there anything anyone has done to reduce the impact of this  
problem?  I already switched from lighttpd to nginx, and I really  
don't want to have to switch it for yet another "flavour of the month"  
web server.
