PyOtherSide does not allow closing to be interrupted.

I am currently working on an application with sub-windows for viewing information about individual parts of a whole system. both the main application and the sub-windows use pyotherside. I have discovered that if I open a sub-window and close it again before all python modules in the Python element have been imported, it causes issues when the sub-window is opened next time. The problem is that the python processes from the original window cannot be stopped on closing and continue running. Depending on the exact set-up of the machine this can stop updates coming to the sub-window through python, or even a crash the whole application.

I have noticed this only in Windows, though I suspect this is just because the Windows version takes longer to import modules.

I would appreciate being able to stop python doing any of its atexit processes until I allow it to procede. This can be done on the QML side by setting close.accepted to false, but this seems to have no effect on pyotherside.
