I think dropping dbcp would be bad - it is something that is familiar to
lots of users.

+1 to including jdbc-pool

Which one to make the default?

My very rough (not really thought out and I haven't looked at the code)
post commons-dbcp 1.4 and commons-pool 1.5.4 ideas are, since both need
a major refactoring, lets use jdbc-pool as the basis for some of that
refactoring and essentially bring the two code bases together.

How viable that is and how long it might take is very TBD.
