> Okay, am trying to reconstruct this from memory as I thought we had a filed a bug on
it months agao when we found it...
> If you use the same Factory from multiple threads it maintains a map of extension namespaces.
When you create a new element it accesses this map and if an addition is going the reader
can get caught traversing it forever. (HashMap is not thread safe).
> This map also keeps all extensions it ever sees, which can lead to a memory leak if you
use the default factory a lot -- say, with hundreds of thousands of extensions in my case.
