TestIndexWriterDelete timed out on jenkins [LUCENE-8678]

From: https://builds.apache.org/job/Lucene-Solr-NightlyTests-7.x/445/consoleText

It does reproduce for me. I vaguely recall there was another timeout failure in this test a while ago.

```Java
ant test -Dtestcase=TestIndexWriterDelete -Dtests.method=testUpdatesOnDiskFull -Dtests.seed=DCF0B4DFB70AB6EA -Dtests.multiplier=2 -Dtests.nightly=true -Dtests.slow=true -Dtests.locale=fr-BE -Dtests.timezone=Africa/Bamako -Dtests.asserts=true -Dtests.file.encoding=UTF-8
```

Migrated from [LUCENE-8678](https://issues.apache.org/jira/browse/LUCENE-8678) by Dawid Weiss (@dweiss)

Start by running the reported Ant command for TestIndexWriterDelete.testUpdatesOnDiskFull and inspect TestIndexWriterDelete.java around doTestOperationsOnDiskFull and testUpdatesOnDiskFull. Compare the timeout stack with the MockDirectoryWrapper.close and TestUtil.checkIndex calls shown in the report. Done means identifying and fixing the cause so the test completes reliably without timing out.
