We want a meaning and unique name for plugin output. For example
./a arg0 arg1 should have a_arg0_arg1.log
./a arg2 arg3 should have a_arg2_arg3.log
I think getpid() and getid() is not unique

This case can be solved by using a shell wrapper, extract args and pass them to 
plugin suggested by Pierrick Bouvier
