You can't have infinitely-lived scripts run within the web server
process. That just isn't supported by the web model. If you want an
infinitely-lived script, you need to run it as a CGI and detach it
from the web server as described here:
http://www.htmlhelp.org/faq/cgifaq.3.html#8

Again, this whole enabled/disabled button thing is not something that
fits into the standard web model. If you need specific help with that,
you need to describe specifically how it is implemented. One guess is
that your script is blocking signals and therefore not dying correctly
when the admin asks for a restart. But that is just a guess based on
very little information.
