There's no need for magic. I think your needs would be adequately served by a service.

Say you call your service/daemon "FaxIt"*,

package FaxIt::Client;

sub new {
   if (...[service is running]...) {
      if (...[service is non-responsive]...) {
         ...[restart the service]...
      }
   } else {
      ...[start the service]...
   }
}

sub send {
   ...
   ...[send request to the service]...
   ...
}
