Maybe you can start a new thread with the ERP check and then detach it.  Roughly:

    use Thread;
    my $t = Thread->new(\&start_sub, @start_args);
    $t->detach;


detach tells a thread that it is never going to be joined i.e. that all traces of its existence can be removed once it stops running. Errors in detached threads will not be visible anywhere - if you want to catch them, you should use $SIG{__DIE__} or something like that.
