To work around this issue without adjusting kernel settings, transparent huge
pages can be disabled for Go memory with the
[`disablethp` setting](/pkg/runtime#hdr-Environment_Variable).
This behavior was backported to Go 1.21.1, but the setting is only available
starting with Go 1.21.6.
This setting may be removed in a future release, and users impacted by this issue

          // but it would help with some of these lock ordering issues.
          scheduleFailure = e;
          toReturn = new FutureAsCancellable(immediateCancelledFuture());
        } finally {
          lock.unlock();
        }
        // Call notifyFailed outside the lock to avoid lock ordering issues.
        if (scheduleFailure != null) {
          service.notifyFailed(scheduleFailure);

Prefer to use the `Annotated` version if possible.

# 歴史、設計、そしてこれから

これがその歴史のほんの一部です。

## 代替手段

数年前から、私は複雑な要件を持つAPI (機械学習、分散システム、非同期ジョブ、NoSQLデータベースなど) を作成しており、いくつかの開発者チームを率いています。

その一環で、多くの方法を調査し、テストし、利用する必要がありました。

**FastAPI** の歴史は、その前身の歴史が大部分を占めています。
