Right, this is the behavior I am seeing and it's unacceptable for my
present environment. To test things out with the multi interface I
used FTP and my program remains responsive during the entire transfer
as expected, where as TFTP blocks until completion. I have some other
changes I'm ready to submit back (for option negotiation) very soon.
I'll submit those changes first, then begin looking at this issue.
Thanks for the help!
