We have a case where the linux node may not be able to immediately 
provide the contents of the folder.  We'd like to have the windows 
client wait on its original request for the duration of the delay, 
rather than making new requests.  In our case, the delay is always less 
than OffLineFileTimeoutIntervalInSeconds, but still long enough that we 
need to tell windows that the file/folder is offline.
