To reproduce the issue:
- Start the ide and create a database connection.
- The node appears in the runtime panel.
- Simulate a crash via Ctrl+C (abnormal exit).
- Restart the ide. The database connection node is
not shown in the runtime tab. (It would have if
the exit was done normally).

The database connection is only an example and
this is not specific to db module.

In general, are the settings and such stored only
at exit time? Is there an api that can force an
immediate save and flush (either for that node or
for all such settings that may be unsaved)?
Or is the save done at regular intervals? If so is
the interval customizable?

A system hang can occur due to various reasons
that are not even related to the ide and
recreating the settings manually again should be
avoided if possible. (If the ide stores the nodes
etc at regular reasonable intervals, that of
course is a reasonable implementation).
