+1! Thanks @s1monw!
I will continue beasting. The failures are very rare now ... I ran 196
iters of slow + nightly Lucene core + modules tests, and hit only ~4
interesting failures.
E.g. this failing seed repros on the PR but not on mainline:
```
org.apache.lucene.index.TestIndexWriterOnVMError > testUnknownError FAILED
org.apache.lucene.index.CorruptIndexException: Unexpected file read
error while reading index.
(resource=BufferedChecksumIndexInput(MockIndexInputWrapper((clone of)
ByteBuffersIndexInput (file=pending_segments_2, buffers\
=258 bytes, block size: 1, blocks: 1, position: 0))))
