Simple patch fixing the issue

The problem is, that the DStoreInputStream waits until > 0 bytes are received, which never happens in case of zero-length-file.

Attached patch is a quick hack to fix the issue. I think that it must be improved in order to also handle error situations: the waitForTempFile() loop must exit in case any error is returned from the dstore side, such as host disconnect.

Committed the patch to fix the original issue:

[199561][efs][dstore] Eclipse hangs when manipulating empty file
   DStoreInputStream.java  1.2

Dave and Xuan please review and improve the fix in order to deal with other error situations, as described in comment #1.
