I imagine that the intention of reading only 100000 bytes at a time is
to limit the amount of memory used by the process. In an environment
where the process is kept around (not CGI, however) doing so might be
critical since it has been alleged that Python isn't particularly good
at freeing memory back to the operating system.

One way of limiting the total size of uploaded files might be to
examine the "Content-Length" header and to reject (ie. not process)
uploads involving files above a certain size.
