Intel SGX 'safe' room easily trashed by white-hat hacking marauders: Enclave malware demo'd

No TSX was disabled on Haswell as the newly-implemented feature screwed up occasionally creating lock inconsistencies. (Disabled in this case meaning fall back to older slower but safe behaviour.) But in principle it's a good idea. Other architectures have had something similar for a while but Intel is playing catch-up again. But Intel isn't as far behind as with NX. You'll find writable non-executable sections in other architectures decades ago.
