Bug#592506: What to do about libtest-harness-perl?

[nicholas at periapt.co.uk]

We have a new upstream version of Test::Harness from CPAN. I have just  
packaged this version and given that this fixes an issue currently in  
test, we need to know whether this should be uploaded in time to get  
into squeeze.

The rough history is as follows:

Current stable version is 3.12-1.
Testing/unstable version is 3.20-1.
As per bug #592506 there is a serious issue introduced since upstream 3.17.
There is theoretically a patch in the upstream repository.
We had 3.21-1 in our repository until today.
Upstream have issued a new release 3.22 that includes the patch.
I have just packaged that into 3.22-1 where it is sitting waiting on  
your advice.
