Kristian Waagan commented on DERBY-4915:
----------------------------------------
I was unable to attach the patch (permission issue in JIRA according to the
error message), but I committed it to trunk with revision 1078608 nonetheless.
I will upload the patch later.
The patch makes the sleep time longer, and it also makes the method try to
delete remaining files one additional time. If the failures persists, there is
likely that a Derby bug is keeping a handle open (timing dependent?).

> 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.
