> In various tests, e.g. {{AsynchronousBufferFileWriterTest}}, {{BufferFileWriterReaderTest}}, or {{HashTableITCase}}, {{IOManagerAsync}} instances are used which are not shut down at all. The only thing cleaning them up seems to be a shutdown handler attached to the JVM. Since each {{IOManagerAsync}} is spawning a number of reader and writer threads, this may put a significant burden on the tests.
