The C++ standard describes the requirements for comparing unordered containers in [unord.req.general]:
> Two unordered containers a and b compare equal if a.size() == b.size() and,
> for every equivalent-key group [Ea1, Ea2) obtained from a.equal_range(Ea1),
> there exists an equivalent-key group [Eb1, Eb2) obtained from b.equal_range(Ea1),
> such that is_permutation(Ea1, Ea2, Eb1, Eb2) returns true.
THashSet should use the same comparison logic.

[util] Obtain uptime from the clock_gettime syscall2025-05-30T23:15:51Zswarmerswarmer@yandex-team.com2025-05-30T22:59:29Zurn:sha1:a07a46cd2b9d577d4945aa186d04d6c0df6ef556
Reading /proc/uptime is about a hundred times slower than accessing the same timer via the clock_gettime call. The latter also has better precision.

better fork-aware pool2025-05-22T12:40:47Za11axa11ax@yandex-team.com2025-05-22T12:00:59Zurn:sha1:c28fa5a5d4eee687fa35713a3b8561b8f892992a
Было: при добавлении-удалении обьекта берем мьютекс, молимся чтобы тот не оказался залочен при форке, никак перед форком на лок не смотрим
Помимо того что это просто не очень надежно, оно не всегда работает. Может случиться так что с мьютексом все нормально, но IntrusiveList все равно [скорапчен](HIDDEN_URL и список закольцован не там где надо (по всей видимости cpu reorder на apple m1 ехидничает).
Стало: берем спинлок вместо мьютекса, в том числе берем его на время форка.

Don't copy a `const char *` into a temporary `TString`, only to convert it back to a `const char *`.
