short:
 that doesn't work

long:
 a method like aclass::amethod(int) has to be called with
an object like x.amethod(42); the signal handler will just call
amethod(42) -- and that wont't work; methods have a hidden 
parameter called this and this is missing ;-)

some possible solutions:
- you have to use "normal" function as a signal handler, but that
  function may call x.method(...) if x is a global object
- maybe a static method may work, but that may not be what you want
