DeVIDE crashes if module reloaded without proper dialog cleanup

[GoogleCodeExporter]

This is actually only a problem in sloppily written modules without proper 
cleanup of child processes.

What steps will reproduce the problem?
1. Allow a a module create a popup dialog (such as yes/no)
2. Do not close the dialog, but select the module on the DeVIDE canvas
3. Reload the module (right-click -> Reload Module)

I would expect the daughter dialog box to be killed - independent on whether 
the module has a special clause for this situation. Instead the dialog remains, 
and the reloaded module is unresponsive. 
If the dialog is closed, DeVIDE comes crashing down.
