Description

I've seen the assert flag a failure for deleteing a log file last night, and a seg0 file the night before.

This is one stack trace:

1) testOSReadOnly(org.apache.derbyTesting.functionTests.tests.store.OSReadOnlyTest)junit.framework.AssertionFailedError: Failed to delete 2 files (root=F:\test\JarResults.2010-11-23\ibm16_suites.All\system\singleUse\readWrite: F:\test\JarResults.2010-11-23\ibm16_suites.All\system\singleUse\readWrite\log (isDir=true, canRead=true, canWrite=true, size=0), F:\jartest\JarResults.2010-11-23\ibm16_suites.All\system\singleUse\readWrite (isDir=true, canRead=true, canWrite=true, size=0)

This is on a machine that I've been able to arrange for a windows machine on which to run the tests for 10.7 nightly, but this is not a new machine. So perhaps the disk - being older - is a little slow in deleting? Perhaps the check can be delayed, or redone if failed first time.

I'm still investigating, checking on hardware settings. The disk scan showed up healthy, and multithreading is not on.
