Thanks a lot  for your answers.

I didn't know that the second reload purges the fun definitions. That
forces me to make further changes to my implementation, as module reloading
is to be expected with some frequence and the time lapse between the
execution of the first and last functions can be big enough to allow two or
more reloads.
