FW: RFR (S): memory handling improvements

[Vitaly Davidovich]

Why is the sys_classpath copied in the first place? Is there a chance it's
modified while this code runs? Otherwise I don't see a reason for it, but I
probably missed something.

Thanks

I found two fixes for memory handling in our (SAP) hotspot code and want
to share this with you:
http://cr.openjdk.java.net/~goetz/webrevs/webrev-mem/

In classLoader.cpp there is a memory leak, easy to be fixed.

In parNewGeneration we allocate the overflow list elements
on an arena. This is faster to allocate and no free is necessary.  It
performed
better with our VM than malloc/free.

I propose to change openJDK accordingly.
