# HOW TO DEBUG:
# Turn on Debugging here in Makefile; change the switches in shared.h (and maybe compile only with one bitsize for speed); and turn on debugging-bool-constant in khoroho.py.
# If multithreading is not disabled, there will be plenty of errors, because sanity checks are done while other threads are active.
