The logback and log4j share the same basic architecture. In principle, anything
you can do in log4j you can do in logback. Rewriting a log4j appender in logback
should be a 15 minute endeavor.
You can take advantage of logback markers so that you can mark the begging and
an end of a section (however long). If the section end without any errors you
ditch the buffered events. Otherwise, if an error occurs, you log them.
This is very similar to your test function, except that markers give you a way
to indicate the start and the end of buffering.
