Writing files on server through CGI

[amaltasb at gmail.com]

this cgi script write different files, request 1 will write 1.html, 2
will write 2.html and so on.
Its not updating the current file.
For example create.py processes a form and write user.html file and
every user is unique.
so if 10 users fill up the form at the same time and click submit
button, can create.py file write 10 html file simultaneously or will
all the request be queued and executed one by one, because at any given
point there can be several users creating this html page.
