The fix looks good. Thanks Bill.

Thanks for the excellent report.  I wish everybody did such well
researched reports!

Yeah, the 2 isn't really needed, because I used "svc_vc_wait" and
"svc_vc_recv" (__func__) to differentiate the 2 messages.

This is really puzzling, since it should never happen.  It's the
recv() with NO WAIT.  And we are level-triggered, so we shouldn't be
in this code without an event.

If it needed more data, it should be WOULD BLOCK, but it's giving
EAGAIN.  No idea what that means here.

Hope it's not happening often....
