Pool is already going forward in the 1.6.x branch and in 2.0.x

It is certainly more work but how much more is the critical question. As
long as the code bases stay broadly similar it should be easy to patch
1.6.x to fix a bug and svn merge the change to 1.5.x. We do this in
Tomcat all the time and merging from trunk (8.0.x) to 7.0.x and 6.0.x is
generally fairly simple. Merging to 5.5.x requires more work as the
source layout is completely different.

Releases would be more work but there are folks that look to be willing
to release 1.5.x and 1.6.x

The other bit I can think of is that the website may need some tweaks to
handle multiple versions. I'm not familiar with the Commons web site
generation process to judge if that is easy or hard.

All that is required for a release is someone willing to tag and release
and three PMC members to vote +1. As long as 1.5.x and 1.6.x remain
broadly similar (i.e. 1.6.x = 1.5.x + generics) then the additional work
of porting fixes between the two should be minimal.

We want to avoid "unofficial" releases. That raises all sorts of red
flags at ASF board level.
