Well it would also be a big optimization if malloc was:

void*
malloc (size_t bytes)
{
 return NULL;
}

But it wouldn't work very well.
 
KDE isn't using threads, just linking to -lpthread. We are actually
using threads for gnome-vfs.

Not useful info unless you track what's causing the mallocs. 

We sort of already expect malloc() use to go up since we are dropping
all the mem chunk BS over time.
