GDK_mmap_minsize again

Hello list,

we were wondering about the purpose of GDK_mmap_minsize when creating transient columns. The attached patch will always *try* to malloc/realloc a transient column but still fall back to memory-mapped files if malloc should fail. This dramatically improves performance. Any good reason why this should not be the default behaviour?
