somewhere in either kernel or glibc we need to do the merging to avoid allocating new vmas and to grow the avl, otherwise server environment will be hurted. We're not going to need this feature to run kde well, or to do compiles, but people using the 3.5G per-task patch or using a 64bit userspace becaue they're too strict in 3.5G are certainly going to strictly need this optimization.
I certainly prefer to do the merging at the kernel layer because it's generic and it doesn't optimize only malloc users.
