Errors in Recipes

I have seen a rule in Python’s Makefile

-PYTHONPATH=$(DESTDIR)$(LIBDEST)  $(RUNSHARED) \
    $(HOSTPYTHON) -Wi -tt $(DESTDIR)$(LIBDEST)/compileall.py \
    -d $(LIBDEST) -f \
    -x 'bad_coding|badsyntax|site-packages|lib2to3/tests/data' \
    $(DESTDIR)$(LIBDEST)

The dash in front of the command is to let `make` never mind the return value of the command and continue executing the next command.

gc.garbage

In my Pyramid view classes, I defined __del__(), and I guess there were reference cycle had been introduced inside the framework (which I couldn’t easily see), so all the view callable objects were not garbage collected.
