📄 Description

If we try to use mmap when the model is larger than the system free space, loading is slower than the no-mmap approach.

This should resolve multiple issues where model loads stalled for longer than 5 minutes on some systems and caused our timeout to trigger. When those users forced use_mmap=false, things sped up significantly, so this should handle it automatically.
