> In some failure modes, the pending creates list is not cleaned up and prevents that file from ever being created.
> When I try to create the file after the first job was killed (hours previously), I get:
> 060404 084619 Cannot start file because pendingCreates is non-null. src=/user/oom/rand/part000118
