Description

It turns out that https://github.com/apache/arrow/blob/673125fd416cbd2e5c2cb9cb6a4c925adecdaf2c/cpp/src/plasma/fling.cc#L63 and probably also https://github.com/apache/arrow/blob/673125fd416cbd2e5c2cb9cb6a4c925adecdaf2c/cpp/src/plasma/fling.cc#L49 can block and give an EAGAIN error.

This was discovered during stress tests by https://github.com/stephanie-wang/
