Valgrind issues in druntime

[Matt Soucy]

Hi all-
I was testing some programs out with Valgrind, when I decided to try to
check a D program I had. I was a little surprised to discover that there 
were a couple of issues detected - and more so to learn that all four of 
them were in druntime. It's only 360 bytes total, but I feel like it 
should be possible to fix them.
Unfortunately, I have never really looked at druntime's source before, 
so I haven't gotten very far with my searching. I found that one of 
these issues has already been submitted, but there's no news since 
October of 2011:

What is the procedure I should follow for this? Mark it as confirmed and 
add the other three valgrind cases?
Thank you,
-Matt
