Okay - by "block" I didn't mean that Zope stops to receive connections or
anything.
I meant that the occuring request (the ones that post's a file to Zope) is
"blocked" so you cannot do anything in that thread while the file is
uploaded.
Your explation on ZServer helped me here Dieter - thanks ;-)

So what I want, is to (while the upload is progressing) read the size of
the temporary file or at least see how many bytes is transfered.
Looks like some patching in ZServer ?

Or is it impossible to do some hacking here ?
