Not yet applied here.

Here my first 'real life' feedback.
I applied the version from early this morning (without the retry sig commented)
to the gcc-boehm in gcc-3.3 branch
In the area of libjava I see a failure reduction by at least 6 TC's.
I continue this evening, also I'll apply this patch and test it.
Thank you for work!
