Detailed Description

The child's pipes are logically separate from the process metadata (they may even be kept alive by the child's descendants). This call lets you manage the pipes' lifetime separetely from the lifetime of the child process.

After this call, the Subprocess instance will have no knowledge of these pipes, and the caller assumes responsibility for managing their lifetimes. Pro-tip: prefer to explicitly close() the pipes, since folly::File would otherwise silently suppress I/O errors.

No, you may NOT call this from a communicate() callback.
