Given that the main focus of JMeter is HTTP, and we use Apache
HttpClient, if we do replace logging it will be sensible to use the
same, i.e. Commons Logging.

But it is a huge job to do this; every single file that uses logging
will need to be updated.

As well as changing all the documentation, config files etc.

Not yet.

I wonder whether there's really any point supporting database pooling
at all, given that the focus of JMeter is on independent test threads.

Adding pooling effectively means that JMeter is testing the pooling as
well as the database.

I don't think database pooling is really necessary for JMeter, so the
performance is not a big issue; tests that want to exercise a database
should not be using pooling - or at least should not be using a
pooling solution which is fixed by JMeter.

I don't know whether it's possible to create a datasource which
includes pooling, if so, then that is the way to go - i.e. support
data sources (I don't think we do currently).
