Hi -- I have a process that runs fine from a unix command line: 
 foo&

[download]
I'd like this to be fired off from a Mason page (modperl2, apache2). This is not on a public site, and  foo& is benign, and foo is smart enough not run multiple copies of itself.

Is 

system('/path/to/foo&');

[download]
a reasonable way to invoke a backgrounded foo from a Mason page, or is something more complicated needed? If so, why?

Thanks

water

Update:

the setsid solution offered below worked fine for me, once I got over a simple (but for me hard-to-find) bug: foo& worked fine from a command line, but wasn't working from w/in mason/apache/modperl because the system had neglected to set a slew of required environment variables. Once I figured that out, and included an appropriate source 

my $rc = system("source /path/to/.profile; setsid /path/to/foo &");

[download]
then all worked great.

Many thanks!
