¿How can it be risky?

If it's risky, and you're trying to activate it with a CGI,
then maybe you shouldn't use a CGI to activate it.

On the other hand, the process could wait for a SIGALRM (alarm).
SO, now, your program can:

1. Setup alarm to signal after X seconds.
2. Sleep forever.
3. Catch alarm, do stuff.
4. Goto 1.

Now, your CGI simply sends a SIGALRM to the process,
which starts the cycle again.

Kinda neato.
