Storing cgi data in stacks

This actually reminds me of a question I have...  what happens if 
many people are attempting to update a page at the same time?

For example, a guestbook CGI script updates a web page.  What happens 
when two guests try to do it at the same time?

Does one get an error?  Does it just "hang" until one is finished?
