Question on forking process

[Benny Ho]

Hi there,

I am new to PERL. Recently I am trying to write a CGI with PERL to call on some system 
task.
The task would take a long time to complete. So I use fork() to create child processes 
to run a subrountine code,
hoping they would run on background and the parent CGI would return the request and 
close the connection.


However, I found that even the parent end, the CGI connect still keep alive.

So, my question is how can I resolve this problem with PERL?
