168 This driver can spew a whole lot of debugging output at you. If you
169 need maximum performance, you should disable the DEBUG define. To
170 aid in debugging in the field, I'm leaving the compile-time debug
171 features enabled, and disable them "runtime". That allows me to
172 instruct people with problems to enable debugging without requiring
