Not at all. Faster because checking for the existence a particular
attribute (the 'hasattr()' function) takes a finite amount of time.
Since 99.9999% of the time it will return True (the False condition
only happens at startup/shutdown), that time is wasted. The try/
except construction allows the call to be made directly, but handles
the few outlier conditions without crashing the program.
