IIRC one of FoundationDB's features is that it does support such transactions, so you can easily implement indexing on top of it.
In pretty much any case, it literally is: you're dynamically linking against the libc. This is a little fuzzier on Linux (because, as you mention, multiple libc implementations exist), but on Windows, macOS, and the BSDs, the only supported way to make syscalls is to make calls into a dynamically linked libc, provided by the operating system.

| You are entering the operating system shell. By confirming this action in |
| the appliance shell you have agreed that THIS ACTION MAY VOID ANY SUPPORT |
| AGREEMENT. If you do not agree to this -- or do not otherwise understand |
| what you are doing -- you should type "exit" at the shell prompt. EVERY |
| COMMAND THAT YOU EXECUTE HERE IS AUDITED, and support personnel may use |
| this audit trail to substantiate invalidating your support contract. The |
| operating system shell is NOT a supported mechanism for managing this |
| appliance, and COMMANDS EXECUTED HERE MAY DO IRREPARABLE HARM. |
| |
| NOTHING SHOULD BE ATTEMPTED HERE BY UNTRAINED SUPPORT PERSONNEL UNDER ANY |
| CIRCUMSTANCES. This appliance is a non-traditional operating system |
| environment, and expertise in a traditional operating system environment |
| in NO WAY constitutes training for supporting this appliance. THOSE WITH |
| EXPERTISE IN OTHER SYSTEMS -- HOWEVER SUPERFICIALLY SIMILAR -- ARE MORE |
| LIKELY TO MISTAKENLY EXECUTE OPERATIONS HERE THAT WILL DO IRREPARABLE |
| HARM. Unless you have been explicitly trained on supporting this |
| appliance via the operating system shell, you should immediately return |
| to the appliance shell. |
| |
| Type "exit" now to return to the appliance shell. |

Cleaned up formattingWhen I first started doing caps-lock-to-control, I mapped my physical control key to caps lock. Eventually, I stopped bothering and kept it as control.
Worth noting that, AFAIK, both of these were removed on aarch64 (and aarch64-only cores do exist, notably Amazon's Graviton2)
I know of one place where Apple does this: in China, and only China, you can buy an iPhone with two physical SIM slots. You can do Dual SIM on iPhones elsewhere, but only with an eSIM.
