Making "read from file" less blocky.

[Alex Tweedly]

Oh, that's a bit worrying .... I'm just starting a project that will use 
httpd, and it might in the medium term need to receive large data sets.

But for now, similar to this case of yours for "serving" files, it only 
needs to send large data sets, and I have tested that pretty thoroughly 
already so I'm comfortable it'll do that just fine.

Alex.
