Comment (by Joel Sherrill):

 I think the next step is to submit a patch to add tests to the fstests
 suite. That way your test case can be run against any filesystem. It
 should pass on all file systems except IMFS at this point. Then we can
 discuss a fix.

 Marking a node as dead is OK but we need to make sure there is a way to
 reclaim that node either for another file or to be freed. I am not sure
 offhand how the directory entries are managed during file creation.

 The one thing we do NOT want to do is accidentally create a memory leak.
