Fwd: Re: [pylucene-dev] investigations

Hello, java@gcc.gnu.org.

I am user of PyLucene lib which was built with gcc/gcj.
I have some interesting question.

Thanks in advance for the answer.

No, but I bet Hans Boehm or someone at java@gnu.gcc.org could shed some light 
on this. Good find !

So far, these leaks have been only been reported on Linux, so it's got to be 
something between gcc/gcj and Linux...
