Is it possible to turn off file upload buffering in nginx?

Hi,

I just wanted to follow-up on an issue that was first
raised back in 2006 - are any options planned in nginx
to allow users to turn off the buffering of file uploads ?

If so do you know the likely timeframe for this ?

Currently this is the only problem stopping me migrating over
to nginx from pound.

See this link for backgound information:

Thanks,
Chris.
