>MimeMessageInputStreamSource (holding the reference to the deferedFile) is
disposed, each references to opened stream get cleaned up, and the file is
*deleted*. We should be good...
Thats what I meant : I may be reading MimeMessageInputStreamSource's code
incorrectly but I don't see a reason that dispose cannot be called by a thread
`t1` while another thread `t2` is trying to read the contents of one of the
inputstream returned by `getInputStream()`
`t2` is going to get `java.io.IOException: inputstream is closed` because
`t1` disposed the message and we are back to data loss territory.
