CGI implements a $CGI::POST_MAX variable which sets an upper limit on the request size it'll handle. Look at that code and reimplement or copy it into yours.

What it sounds more like you're in search of is being able to configure your web server to disallow requests over a certain size, but if it can be or how that is done is going to vary from httpd to httpd (for example, see LimitRequestBody for older Apachen).
