Hi,

one more problem I ran into is memory exhaustion when using XCore.

Having some XCore models in different plugins, some depending on each other,
all open in the editor, Properties- and Outline-View open.

---

As long as i don't change/save any of my XCore models, memory usage
stays stable.
Three days of work, without Eclipse restart, no changes to any XCore
model, memory usage is stable.

---

As soon as i start to modify my XCore models, edit* and save*, memory
usage goes up and up, on every save/build.
Nearly nothing else is changed in workspace, i only work on the models.

After some time of work, depending on the model edits/saves and the
memory i gave to Eclipse, it reaches max memory and then the XCore build
stalls and only a Eclipse restart helps.

---

To check this problem, I have used one of my (bigger) models, take a blank
line in the model and add a blank char + save, doing this over and over
again ...
You may see sometimes "User Operation is waiting", go on and add/remove a
blank char + save.

Memory usage goes up and up ...

thx

Please open a bugzilla. Likely the old inferred objects that are
discarded each time the model is change (on each edit) are being locked
in by some map that should be cleaned up too.
