Under normal circumstances, what you've done (in particular, closing STDOUT and STDERR) should be sufficient to detach a forked CGI script.  In order to further debug the issue you could try lsof — e.g. lsof -p<PID> to show files/pipes/etc. associated with process number PID (i.e. your CGI process that presumably causes httpd to hang).

BTW, what's the exact context? Is this a regular CGI script, or called from within a mod_perl handler, or are you running the CGI script via mod_perl registry, etc.?  Is there a database involved (DBI/DBD::*)?
