Making "read from file" less blocky.

[Tom Glod]

Hmmm.... interesting.

I was sending binary variables to it, and the headers came through ok, but
the binary data didn't when it was over a certain size.

What sort of data sizes have you been been sending to your httpd standalone?

My tests, were 18 months ago at least, but I am hoping it was just me doing
something wrong.  I did see a "//todo" in the library code under a section
that looked like it dealt with multiple chunks.
