[pstricks] Returing arrow

[Andreas Gising]

Hello!

I need to make an arrow returning to the same box it comes from. I would
also like to apply a label to that arrow.

I have a \psidiabox representing a 'wait'-function.
\ncline lookes like crap, because it makes an arrow straight across the box,
and \ncbar does not allow labeling?
Suggestions?

    \psset{shadowcolor=black!70}%
    \begin{psmatrix}[rowsep=0.5,colsep=0]
        \label{flow:sync}
        \psovalbox[fillstyle=solid,fillcolor=blue]{Start} \\
        \psframebox[shadow=true]{Start reception cycle and counter} \\
        \psdiabox[fillstyle=solid, fillcolor=blue]{Counter = 70ms ?} \\

        \psframebox[shadow=true]{Collect results} \\
        \psframebox[shadow=true]{Start new reception cycle and restart
counter} \\
        \psdiabox[fillstyle=solid,fillcolor=blue]{Received a pulse?} &
        \psframebox[shadow=true]{Out of sync, counter += $\delta$} \\
        \psdiabox[fillstyle=solid, fillcolor=blue]{Counter = 70ms ?} \\
        \psframebox[shadow=true]{Collect results} \\
        \psframebox[shadow=true]{Start new reception cycle and restart
counter} \\
        \psdiabox[fillstyle=solid,fillcolor=blue]{Received a pulse?} &
        \psframebox[shadow=true]{Out of sync, Counter += $\delta$}\\
        \psframebox[shadow=true]{Sync is OK, tune} \\
        \psdiabox[fillstyle=solid, fillcolor=blue]{Need tuning?} \\
        \psframebox[shadow=true]{Counter $\pm=\frac{\delta}{4}$} \\
        &\psframebox[fillstyle=solid, fillcolor=green, shadow=true]{Tuning
is good}
