[logging] logic for determing log level

[__matthewHawthorne]

This is a general use question about [logging].  I'm looking through the 
source for [betwixt], and I see lines like the following:

if ( log.isTraceEnabled() ) {
  log.trace( "Is " + descriptor + " empty?" );
}
What is the purpose of doing this check?  If trace *is* enabled, then 
isn't the same check done inside of the underlying logging implementation?

Is this some type of trick to improve performance?  I'm probably 
misunderstanding it, but I just think that it adds clutter.

Any insights?
