Out of Memory - Slow leak?

This is a continutaion of Issue 61 - unfortunately it doesnt seem that the fix in 2.2.9_03 has fixed the problem.

Does it have queue and cache ? 2-) Can we give privileges to users , for example some users can only read some fields and some just can write java fields. Some users only allowed insert ability. ...
