Another way, that is easier to control, is to use mutexes.
Mutex is a place in memory that is locked until someone free it. So
you can check if that place (usually mapped to a name, alto I do not
remember at the moment how Linux implement it) exists, and if so, you
stop your own execution, otherwise you can continue the loading.

The simplest solution: let program check if /tmp/<filename> file exists
and create it,then on exit delete.If file exists then instance is
already running.
More complex would be using IPC (maybe others could describe)
