>            Priority: Critical
> RCFile is not thread-safe, even if each reader is only used by one thread as intended,
because it is possible to return decompressors to the pool multiple times by calling close
on the reader multiple times. Then, different threads can pick up the same decompressor twice
from the pool, resulting in decompression failures.
